Brackish to Marine Moray Fdg. 12/24/06
Hi I was wondering what non live food I should feed my freshwater (brackish)
moray eel.
<Mmm, most anything discrete (that holds together), meaty, that it will take...

Moray Eel in Fresh Water 10/10/06
Hi Bob I wonder if you can help.... <Hi, Chris here> I'm what people like to
call an "impulse buyer" which I know is bad when it comes to fish. <Yep> Right
now I have cichlids no bigger than an inch and a half. A paroon shark 2 inches
at the most, and stupidly I went to the fish store and they had just gotten
eels. <Uh oh> I picked the 'pretty one" which was brown with yellow spots. Its
Gorgeous! I asked the people at the supply store if it was in a brackish tank...
I though this was logical. They told me it was
FRESHWATER so I bought it. <Oops> I have a 60 gallon tank that is very long so
there is room for him and I have rocks with caves and driftwood and plants for
him. I know I will have to upgrade to a 125 Gal eventually but they seem happy
for now. So in doing research on the net I learned the eels are brackish... I
want the best possible home for my fish and won't give it back to the store
because they are obviously worse off than me. I asked what kind of eel and they
said moray. Asked again if he was in brackish water and they told me freshwater
is fine for them. They also said he'd be fine with my cichlids because they are
too fast for him...
I am planning on feeding him ghost shrimp, minnows and vary with frozen large
shrimp and whatever I can get my hands on or I think he'd like... So any advice
you can offer would be great! I need it!
<These Eels need brackish water when young and a marine environment when they
mature. Please read

Raising pH in Brackish Tank, "FW" Morays 7/11/06
Hi,
<Hi John, Pufferpunk here>
I am writing with a few questions for anyone who may have the time to answer
them for me. All help is greatly appreciated.
<I can certainly try!>
I have in my possession a "Freshwater" Moray Eel, about 14 inches in length. He
is currently in a 55 gallon tank (48"x12"x18") with about 1/2" of gravel on
bottom. I saw him for sale a while back and did some research on him before
making the decision to purchase. The specific gravity of salt in the water is
1.008, according to my recently purchased hydrometer.
<I prefer refractometers--much more accurate--hydrometers can be off as much as
.005. You might want to compare the reading on your hydrometer, with a
refractometer, to see if it's true.>
Ammonia, nitrite, nitrate levels are all at zero. I believe the pH is a little
low for him, ranging at just over 7.5. I've had him for just over two weeks now
and am having problems. :(
My first question is should I raise the ph level?
<I would, BW fish prefer a pH of around 8.>
He is a lone inhabitant, other than food (a few guppies ranging from very small
to about an inch in length and a few ghost shrimp I put in yesterday). I'm not
sure of the exact pH level he would be happiest in so I figured it wouldn't hurt
to ask.
Second, would he be happier if I kept him on live or switched him to frozen? I
bought some frozen krill for him but he isn't taking to
that very well. If it's better for him to be on frozen, what is the best way to
switch him to frozen? One person I talked to said that I should not let him eat
one day, then try frozen the next and if he doesn't take to it then give him
some fresh and to just keep trying that making the gaps in-between feedings
longer, until he breaks and eats the frozen krill.
<You will have to "train" him to eat frozen foods (hopefully you are defrosting
before feeding). You can spear the food with a wooden stick (like the ones they
use for kabobs) or you can get a plastic one at your LFS. I'd take away his
live food for about 3 days before trying this. Then you will have to entice
him, by wiggling the food around by his face (preferably in the evening, during
"regular" hunting hours). You could also bounce the food off a thread (use a
needle to go through the food) but don't tie a knot in the end. I would try a
variety of foods, including silversides, people shrimp & any other odds & ends
you see for sale in your grocery/produce store.>
My other problem is with his breathing. He is breathing rapidly with the same
symptoms of another eel I read about in one of the FAQ’s on your site but I
don't believe that low salt is the problem. Like I said the salt level is at
1.008 SG. What else could possibly cause this breathing problem? He is not
eating as much now as he used to. Is it because I'm trying to switch him to
frozen or because he is sick? He is displaying no outward signs of any parasitic
infestation or bacterial infection. Is there the possibility of internal
infection?
<Heavy breathing can be a sign of ammonia/nitrite issues, affecting the 02
levels in the water and/or burning their gills. How long has that tank been set
up? Are you doing regular weekly water changes? You should be seeing some
detectable nitrates in a cycled BW tank. How was the tank cycled? How quickly
did you raise the SG? It should be only raised by .002/weekly water changes so
as not I'd test the water again.>
My last question is due to fact that he is a brackish water fish.
Could I put substrate at the bottom of his tank instead of the standard fish
gravel that he is in now?
<This actually goes back to your pH question & how to raise it & keep it stable
around 8. It is recommended to use crushed coral or aragonite as substrate in a
BW tank. Since you only have 1/2" of gravel in there, you could just add
another inch to that. If your gravel is dark though, you may not like the look
& want to change it out completely for the buffering substrate.>
He seems to be doing just fine with the gravel--he is burrowing down under some
rock I have in his tank during the day. Kind of like a natural rock structure
that he swims through and sleeps under.
<Yes, they hang out in burrows during the day & hunt at night.>
I have some knowledge about aquariums but I don't know everything
<Ha, me either!>
and hopefully you guys can help me learn a little more about this guy. I've had
him for just over three weeks now. Anything you guys can share is greatly
appreciated. Thanks for your time and have a great day.
John R. Ayer
<Thanks John I will (today's water change day) & enjoy this interesting
creature! ~PP>
Why To Research BEFORE You Purchase - A Perfect Unfortunate Example - Not so
FW eel... 06/14/2006
I have a fresh water tank and just bought a snowflake eel. It's a 55 gal.
tank and I read on your website that they should have at least 1.005 salinity in
the water.
<Please.... learn about your animals BEFORE you purchase them.... I see this
going somewhere I don't like....>
My first question is that I have many freshwater fish in the tank like a discus,
2 pictus catfish, 2 paradise gourami, a blue and gold gourami, 2 Plecostomus,
African butterfly fish, tinfoil barb, Bala shark and two angelfish.
<A slightly incompatible mix to begin with - that tinfoil will outgrow the tank
and should be in a group/school, so will the plecs outgrow the tank (eventually
- they'll be fine for a good long while), the Bala is a schooler that should be
kept in a group and which will also outgrow the tank (much faster than the
plecs), and the discus, a very shy, retiring animal, really isn't compatible
with any of these, save perhaps the gourami and the pictus. It's unlikely to
become bold enough to get enough food in this group.>
Will raising the salinity as you say to 1.005 or 1.010 bother or be fatal to any
of these fish?
<Fatal.... to all.... The snowflake is entirely incompatible in this
system. Your current animals CANNOT tolerate the amount of salt the eel will
need as it grows. It should, as an adult, end up in fully marine conditions.>
Secondly how do you go about raising the salinity up to this point 1.005 or
1.010 without stressing the fish.
<Forget stressing.... you'd ultimately kill the current inhabitants if you do
this. 1.005 for a couple weeks might only damage them, but beyond that will
come to a point that they can no longer survive. Truely freshwater fish are NOT
brackish fish, and brackish to marine fish, like your eel, are NOT freshwater
fish. These animals are simply and completely incompatible.>
I saw that you told someone not to exceed jumping .002 at a time. So I guess
really my question is can you tell me step by step how to raise the salinity in
my tank without hurting my fish,
<Can't.>
and if you could please tell me step by step what I need and how to do this
because I will admit I am clueless about this.
<Read.... Research.... And most of all, NEVER buy an animal without first
learning its needs and considering whether or not you can realistically fulfill
those needs. These are lives.... living things.... please treat them as
such.>
Thank you. I would really appreciate if you could answer this E-mail as soon as
possible thank you.
<We answer all as we can. Wishing you well, -Sabrina>
Why To Research BEFORE You Purchase - A Perfect Unfortunate Example - Not so
FW eel - II - 06/15/2006
First thank you for responding , but I got 2 say
<Please.... to, not 2.... All correspondences are presented on our
FAQs pages, please don't use "netspeak"/"webbish"....>
I do not like you implying I don't think of these fish as living things
and that their lives are important because I love my fish and there lives are
very important to me. So I did not appreciate the implication that I do not
treat them as living things and care about them because I do!
<A wise fellow once tried to teach me that one of the first steps to
loving something is knowing and understanding that thing, and having trust in
that knowledge....>
Secondly that so called "incompatible mixture" as you say has been
eating and doing well together including the discus, thank you very much, and if
I may add are very healthy.
<.... this is an incompatible mix all the same....>
Secondly the guy I bought the eel from said he was a freshwater eel and
did not mention he would become a brackish water eel as he grew.
<And again, I'll suggest that you research PRIOR to purchase.... Even
if I tell you, with extreme confidence, that an animal is safe for your system,
I'd prefer that you confirm it with more than a couple of sources....>
I am going to try to correct the problem without hurting ANY of my
fishes lives, even if I have to give the eel to someone who can care for him
properly.
<I'm very glad to hear/read this.>
Thirdly can you please tell me if regular aquarium salt will help the
eel any.
<Mm, not a great deal.... Aside from that, though, any amount that
would be of "real" benefit would be of harm to your other livestock, or at least
not appreciated by them.>
Thank you.
<All the best to you, -Sabrina>
Re: freshwater moray eel help
thank you for the very quick reply I've found a moray eel called the
White-Cheecked Moray Eel or the Echidna rhodochilus can you please help me
find one? I live in Oldsmar Florida if their is any shop or website that

<Not a freshwater species... did you read where you were referred? Use
your Yellow Page phone directory to call about for local stores. Bob Fenner>
Ongoing NOT freshwater moray eel help, ongoing poor English and
refusal to read 4/15/06
I have found info about the Echidna rhodochilus and it says that it
only grows to 14" but other people say that it could grow bigger than that
and would
a pleco live with it do to the salinity?

Info about Gymnothorax tile eel 2/10/06
Greetings,
<Salutations>
I have a Gymnothorax tile eel AKA (Freshwater Snowflake Eel) and I have
questions concerning his well being. Right now he lives in my 45gal Brackish
water tank and seems to be doing quite well. I have had him for nearly 8 months
and he is currently on a diet of squid.
<Need to expand this diet>
However I did some research on him and several article say that this species
does better in a marine type environment.
<Some do... with size/growth>
Is this true? Second most of my research says that this particular species can
survive in a brackish environment but not for long term. I currently have a
65gal saltwater tank that I am currently establishing that at this moment has no
fish or animals of any sort. My question to you is this, would my Gymnothorax
tile eel do better in a marine type environment or can I leave him in his
current brackish water home?
<Would be better in all marine>
Second, if I were to transfer him to my marine aquarium can you recommend a
procedure to minimize the stress on the animal?
<Matching present spg, increasing some 0.001 to 0.002 density per week by
adding/changing out water of increasing saltiness>
I have done a lot of research on this animal but it is hard to separate fact
from fiction. I would hate to loose him due to my ignorance.
Many thanks in advanced

Hi My Name is Britny, I have a fresh water snow flake eel, 2/8/06
<... there isn't any such animal>
I noticed that one of his gills doesn't look like it is working properly, the
one side looks like it always has. working, the other side doesn't move at all.
Could this be from the water condition, or do you think it is because he is
sick?? Its weird he seemed to be fine then like I said I just noticed that only
one was working. If you can help by giving any reason why this would happen it
would be really helpful. Thanks

Freshwater moray eels... actually brackish 11/18/05
Hi-
I have a 180 gal. tank that I've had for a long time. My fish have been thriving for many many years. Three years ago I felt really sorry for two "freshwater" moray eels in a shop in a tiny tank. They looked terrified and had no shelter. I know from
scuba diving that they like to stay in caves or overhangs and I could tell these guys were miserable and terrified. I went ahead and bought both of them, then went on the internet to see just what I needed to do for them. I upped the salt in my tank to one tablespoon to 5 gallons. My other fish are doing fine after three years. I have
Jurupari, one mono, and one "fat" goby. So the eels have been great and happy-- they each have their own cave, they were eating calamari, shrimp, krill, salmon and smelt.
<Me too!>
I know they can go a few weeks without food, which they do sometimes. They are off the food again. The problem is that for the last two and a half MONTHS they haven't eaten, they go into one cave together (which they NEVER would have done before), one has a swollen throat, the other has a lump on his chin,
<Likely goiters... from a lack of iodine (can, should be administered exogenously) and the cumulative effects of life in too "fresh" water>
and they are just acting very strange. The goby is looking grayish (he's a dark brown normally) and his eyes are a little cloudy. The eels and the goby won't eat and the other fish seem to be ok. The water tests are all fine. I've upped the salt to one tablespoon to two and a half gallons of water and upped the temp to eighty five. A week later, they still don't look good. If you can help me with this I would appreciate it greatly.
Also, do you know how long "freshwater eels" live?
<Years when kept in brackish (spg of 1.005-1010) to marine (as adults) water>
Thank you very much—
Dana Mardaga.

Fire "Eel", Eye Damage - 10/12/05
Hello
<Good morning.>
I hope you can help me to help my Fire Eel. When we were cleaning the tank 10 days ago, my eel got a fright and decided to have a 100mph swim round the tank!
<Yikes! Hopefully this system is not too small for him to feel secure....>
I think he must have hurt himself as I have now noticed that his one eye is totally white (looks blind) and he has a patch above the eye which seems to be getting whiter by the day.
<Definitely a concern.... Probably did scratch/damage himself during his speedy stint about the tank.>
He is also off his food, not having eaten for three days (very unusual for him).
<And not a good sign....>
I have bought some Potassium Permanganate (Condy's crystals), but don't know if I can use this as he is 'scaleless' and I have been told to be careful of medications as not all are suitable for eels.
<You are correct. Do not use this.... Very, very caustic - will more than likely kill the eel, and can be hazardous to deadly even on stronger fish.>
Please help. I am worried about my fat boy!
<Bob's recommendation (and I agree wholeheartedly) is to add aquarium salt (the stuff marketed for freshwater aquaria, not marine salt), perhaps at one or two tablespoons per ten gallons, possibly also add Maracyn I & II (erythromycin and
Minocycline) as a preventative.... and of course, maintain optimal water quality. Try feeding stinky, attractive foods like bloodworms (live if you can get 'em) or even redworms/tiny earthworms you collect yourself from an area uncontaminated by
pesticides/herbicides.>
Thanks, -Wendy
<Wishing you well, -Sabrina>
PLEASE HELP Gymnothorax polyuranodon QUESTION 8/20/05
Hello I have a question regarding my eel (Gymnothorax polyuranodon). I
bought it as a "freshwater moray eel" but I now realize its brackish/marine
nature.
<Yes>
I have had this eel for about 6-8 months (with my African Cichlids) and
It has been a complete pleasure. It has a nice cave and plenty of hiding
places. It has had a fierce diet for night-crawlers (about 2-4 daily), and has
eaten regularly since I brought it home. It killed my biggest fish, so I
assume it was healthy and comfortable.
Now the problem. For the last month and a half, it has stopped eating. It
still swims and appears healthy, but occasional heavy breathing has gotten me
to believe its "freshwater stint" is about over.
<As is its life... internal damage... renal...>
I have added sea-salt, but
nothing major. He sits vertically towards the top of the tank.
I want to get this eel to a brackish/marine environment, but I have nowhere
to send it. Do I find a local fish store/aquarium??
<It's very likely too late>
Do I send him to
brackish or marine? Is there some sort of rescue center?
<... no>
I'd like to know your
opinion, since no one really seems to know anything about this at the local
fish stores. I appreciate any feedback.
<WWM is, by design, a stop-gap attempt at informing (and inspiring) folks as
aquarists... to avoid such mistakes as buying inappropriate livestock,
mis-placing it... Bob Fenner>
Re: PLEASE HELP Gymnothorax polyuranodon QUESTION... "snapping out of it"
8/22/05
<As is its life... internal damage... renal...> Internal
damage? Renal??
Please explain.
<<Kidney damage from being in a non-brackish setting... evidenced by its current
behavior>><It's very likely too late> And if it's not too late...what then? I
can't
just do nothing.
<<There is little to do practically... you could try moving this animal to a
cycled, stable brackish setting... but it is very, very likely too damaged now
to recover>>
So you're saying it's as good as dead, but you hardly explain why. Isn't it
true that this type of eel stops eating for extensive periods of time
without reason? Could he snap out of it?
<<? "snap out of it...?" ... not likely... This animal was destroyed by being
mis-placed... Next time, research your species, its needs, and supply/meet them.

Grass Eel 7/12/05
Ok, I didn't see this in any of the FAQs, but, I have just bought a grass
eel. From what the guy at the store said, they are freshwater, and I have a 50
gallon tank of guppies, he said they would be fine together. Well, I have a lot,
and they came from 3 guppies saved from my turtles. I wouldn't want to see
them get ate. I can't find any info on them. Any help would be great.
Thanks,

Fresh Water snowflake ell 7/6/05

Gymnothorax polyuranodon Problem
Hi,
<Hi, MikeD here>
My name is Natalie and I have had a Gymnothorax polyuranodon (freshwater
moray eel - I attached a picture in case my observation of his species is
incorrect.) for almost 3 years now- possibly a bit longer. He always eats
regularly and even catches live silvers/shrimp/crawfish himself. He is a
healthy weight and length and I have not noticed anything different with him
until today. The tank is a mix between totally freshwater and brackish. (I
add about a half a cup- a whole cup of salt in every other week.) When I do
he swims figure -8's through it as it dissolves then goes back to his den.
My other fish also seem to like the extra salt- I was told this is due to
easier breathing on there end- I assume it helps the gills. I have a 55
gallon and it is inhabited by the eel, a convict, a Texas cichlid, a jack
Dempsey, and a Firemouths. They have all been together since the start and
all get along well. My problem is the eel (as I noticed today) appears to
have enlarged gills. They are normally a bit bigger when he breathes heavy
or eats- but now they look swollen and a pinkish/whitish color. I dropped
some platys (he loves them so gets them as a treat every now and again) into
the tank to see if he'd eat. He won't even touch his favorite food!! He
normally chows these even when he's not that hungry. I had the water tested
earlier and it is fine... what could this be? Can it be treated? he is also
breathing very heavy- not at all in his normally calm state. And although,
normally nocturnal, my eel swims about all day long- now he is just laying
over one of the rocks. The only time he lays around is in his den. Not
stretched all over the tank appearing effortlessly helpless. What can be
wrong? The gills are the only noticeable difference as of today. Please, any
input would be appreciated.
thanks in advance,
Natalie
<Well Natalie, I suspect that your problem is twofold, one an error in
terminology and two a matter of time.
Many "freshwater" species, yours included, are actually fish with a two part
life cycle that leave the sea and enter a "brackish" environment to spawn and
reproduce, but many eventually need to return to the sea.
Your other fish are true freshwater fish, and like most actually still benefit
from the addition of a small amount of salt which selves to improve electrolytes
and to retard fungus while your eel needs a LOT more salt and a different type
altogether.
Morays are among the toughest of fish, but even so You're extremely fortunate
for yours too have lasted as long as it did in the environment that it's in.
In truth, it's doubtful that your eel will improve unless moved to another tank
with a true brackish or even better, marine conditions.
By raising the specific gravity to about .0019 to 0124 I believe you'll see a
drastic improvement, but again, that would be fatal to your other current fish.
The list of fish that would make suitable tank-mates is actually large and
includes Datnoides (Siamese Tigers), Archerfish, Monos, Scats, one family of
cichlid called the Chromides and even common mollies.
I know this isn't the answer that you were seeking, but in reality your little
eel needs to return to the sea or at least something much more akin to it than
it's current home.
Hope this helps and good luck.>
Help my dying eel
Bob,
My freshwater snowflake eel is starving to death. Why wont she eat? I have tried
to feed her shrimp, plankton and squid, all of which the other eel, which is the
same as her, has eaten readily.
>>
As a semi-stopgap measure, do try soaking the food in a "baby vitamin"
mixture (to boost its palatability) and lowering the system temperature (maybe
just by leaving the lights off by day?). As the last desperate effort, do
consider "force feeding" the specimen... with a plastic syringe,
dropper, and finely minced food... using a net, wet towel, and someone else to
help hold the animal...

Brackish Fish?
Hey guys I've recently purchased a freshwater snowflake eel. Which in my 55
gal. brackish tank w/bio wheel had them for 2 days, and he/she is about 18 inches long. And
I've transferred some real fresh water fish to brackish. Which
some pets stores say ya can't do! But the main Question is: is it best to have the eel by it self or can they do well in a
community brackish tank?
<Some fish can tolerate more salt then others. South American fish and many catfish have problems with salt. Others seem to be unfazed. There is no specific gravity specification of salinity for the term brackish so it is used pretty loosely.>
And do they eat at nigh? In your forums I've read that some are they are kind of
blind. What I have in the tank is Lionfish (rock fish), South American leaf fish (bush
fish), Plecostomus, American an African Cichlids, Bala Sharks, Clown And orange finned loaches,1fairly large tin foil, dragon fish, green spotted puffer
and a Gourami! Which are all doing fine in the brackish tank, I added salt slowly to make
'em that way. Is that to many fish to make my Eel unhappy?
< Eels I don't think care one way or another.>
He seems fine, hasn't eaten yet that I know of but pet store said he ate two days
ago. Don't have Any PVC in the tank but lots of places to hide. Has taken over a
tree stump ornament , new to eels but have read a lot of info on 'em, what is
their favorite choice of food? Got rosy reds and ghost/glass shrimp in tank, is
that suitable diet? how often do they eat ? And are they a nocturnal?
And are they best kept alone in a 55 gal. tank, which I plan to purchase soon just
for him? Thanks James
< Most eels are ambush predators that are most active at night. Feeding the food items at dusk are probably best. Try washed night crawlers. The shrimp is worth a try. Sometime all they will eat are feeders.-Chuck>

Hello,
<Hey, Mike G here. For future reference, please do not type in all caps. I had to retype your entire query, and this was time that could have been spent helping someone else.>
I just bought my husband the eel he has always wanted. But now we have a problem. We have no idea how to take care of it.
<That certainly is a problem! Hopefully this will teach you to research a fish and ask these questions BEFORE you purchase it. But, it happens to the best of us.>
I have read over your web site and need a very straightforward answer to two questions.
<To get a straightforward answer, you need to ask straightforward questions. You see, not once in this email have I read what type of eel this is, which really does not help me at all.>
Do I need to put salt in this tank?
<Depends on the eel, though in most cases, yes.>
Can my Angle-Fish and Pucstamis survive the salt?
<Well, I think I can safely assume you mean Angelfish for the first one, but I have puzzled over the second for a very decent period of time. Finally, I have come to the
conclusion that you mean Plecostomus, but that is a shot in the dark. Angels do not prefer salt in their water, they are soft-water fishes, but
Plecostomus could tolerate a bit of salt. I'd be mostly concerned about the eel consuming his tankmates. Best of luck, Mike G>

Moray Eel !!!! FW, Brackish, Marine? The blame game
I have today purchased two Moray Eels from one of our local fish stores..(
the manager of the store apparently has no clue about fish). When arriving home
with the Morays (2) we floated them in our tank for an hour before their
release... We have a Pike (6 inches long), Pacu (about as big as an adult males
hand), Catfish (2 about 2 inches long) and a Texas Gar (8 inches long) in this
tank also... We keep aquarium salt in our tank and the water was tested fine!
<How much salt? What is "fine?">
no medications are in this tank....A few hours after being released we noticed
they started to change colors (white) and looked as if they were shedding (white
slimy coat build up).... I, not knowing any different went to take a nap... Upon
waking I went to check the two newbies again to see if they were ok....They were
not...I immediately took them out of our 55 gallon tank and placed them in our
ten gallon tanks. (we have two one is a cichlid tank the other is a gold fish &
tetra tank) (separated one eel in each tank) All of their
shedded like skin has come off now ( it floated in the water like white flakes
when it fell off)(this was about an hour after being in the ten gallon tanks)
and one appears to be doing a lot better.... The other still keeps turning over
on her side..... Neither of them are moving a lot...And both seem to be gasping
for air with their mouths open wide (my tank has over and under water filtration
along with bubble walls so there is plenty of air in the tank).... What have I
done or what can I do to fix whatever problems that are going on?
<... did you happen to ask what sort of water the fish were in at the store? Or
test it on arrival?>
What is the perfect climate for a Moray eel....These are so beautiful with their
gold markings and patterns... I spent a lot of money for these fish and would
not like them to die....Please respond quickly because I don't know what to do
at this moment for them...THANKS!!!!!
This picture looks just like the one that I think is a female....But the other
one has a lot of gold spots that look like clovers or cauliflower markings....
<Mmm, this image was lifted from our site... you should read about this and
other "freshwater" (they're not) Morays:

Scorpion fish and converted "FW" Moray together
Hey what's up,
<Not much (buttercup)>
I was wondering. I have a freshwater snowflake eel {Gymnothorax
tile} to be exact. I have converted him to full marine. Can I get a scorpion
fish
that will live with him in harmony? Oh one more question can you give me all
the information I need to know about a scorpion fish? And is it more
aggressive than a lionfish?
<These two can likely go together. Please read re them by using the search tool

Gymnothorax tile 12/24/04
<Hi, Pufferpunk here>
Three weeks ago I bought a G. tile at my local pet store. It was in a
freshwater tank. I did not know it was a brackish eel. Will it live in
Freshwater? I have had him in freshwater for three weeks and have not seen him
eat yet. I have tried Mysis shrimp, krill, feeder guppies, goldfish,
silversides. I have tried feeder prongs to hand feed it. I would like to find
out what to do to get it to eat. I also would like to keep it I freshwater.
Please help
<The "freshwater" snowflake eel, Gymnothorax tile, reaches about 26 inches in
length. Although seen for sale in fresh water, this is a brackish water fish
just and is not found in freshwater in the wild. They must be kept in BW, which
means using marine salt & measuring it with a hydrometer. Don't raise the
specific gravity more than .002/week, or your freshwater bacteria will die off
too quickly. these fish have been known to not eat for several weeks after
being put into a new tank. Try putting a piece of shrimp on a stick & wiggle it
on front of the fish. You'll have to be patient. ~PP>
"Freshwater" Snowflake Moray Eel 12/14/04
Hey,
<Hey yourself, it's Pufferpunk here. I must request that in the future, you
write your questions with the proper punctuation & capitalization. These
letters must all be corrected by us, as they will be put in our FAQs. This will
take away time from my answering other people's questions.>
I am thinking about getting a freshwater moray snowflake eel. Would it go in an
African cichlid tank? I have Malawi cichlids in it. I have the salinity to
about 0.009.
<Do you mean 1.009 (1.000 is freshwater)? Are you using marine salt? You
really shouldn't be, as Malawi cichlid salt is different. I would not mix these
2 species. The most commonly sold "freshwater" snowflake
morays (Gymnothorax
tile), although seen for sale in fresh water, is a brackish water fish and is
not found in freshwater in the wild. To make water brackish, you need to use
marine salt. It will also eat any fish they can fit into it's mouth.>
Best regards, Miles
<good luck with your fish. ~PP>
Echidna rhodochilus
<Hi, Mike D here>
I have a sort of strange question. I was wondering if you knew how many breaths
a min. my 24 inch Echidna rhodochilus should be taking.<You're right, it's a
strange question>
He takes about 40 per min. now and has done so every since I bought him, the
lady at the pet store said this was fine. I have him in a 150 US gallon tank
with aquarium salt.<I'd check to make sure your water parameters are in line and
the temperature as well. High ammonia, nitrite or nitrate levels will ALL make
a fish breath at a higher rate, eventually resulting in death in severe cases
(particularly the ammonia and nitrite, which should both be 0). Higher
temperatures also increase respiration as the warmer the water, the less oxygen
it holds. The mid 70's is usually good.>
Thank You

Brackish to marine eel in FW: might be too late
Hi, I just found your site. I have a 110gal freshwater tank with Oscars, Arowana,
polypterids. I also fell in love with a snowflake eel. I use the one
table spoon/5 gal salt rule.
Problem. The white slime! It appeared very quickly. About three days and he was
in big trouble. It is killing my eel. It may be too late. Is this normally
caused by a parasite or bacterial infection? And how can I tell?
<This animal is in a non-viable environment... I would remove it, take it to a
store, other aquarist with a serious brackish (spg. 1.010 or higher) or marine
set-up. NOW>
I have brought the salinity up, but I do not want to cause my other fish any
harm. Is there a place where I can see magnified images of parasites? Is there a
way to determine if it is bacterial? What kind of treatments can I expect to
admin?
Thanks
Chuck
<No treatment... what you describe is an environmental reaction... akin to your
opening your eyes in soapy water.>
PS we can trade you for any cornsnake Q's
<Ahh, beautiful animals. Bob Fenner>
Re: might be too late.
I have checked with the store and we tested the water that theirs are in
and it is very freshwater. They have them there for at least 3 weeks. They
have no such problems. I am afraid that what ever it is will eventually work
at my other fish. Is there a parasitic or bacterial element that I might
want to know about?
<... Perhaps I've been a bit too hasty... Please read here on WetWebMedia.com re
"Freshwater Morays" and Echidna nebulosa... do you see the species you have
listed/pictured? Plug this name into Fishbase.org and voila (!), read about the
life habits, habitat of your specimen. Bob Fenner>
Re: might be too late.
PS, I will remove animal to a more qualified keeper ASAP.
<Good idea. A very great many "inappropriate" animals are sold in the trade, and
many more that might be well-husbanded to folks that don't have the background
to decide, provide for them. Little of this occurs at the express consent,
knowledge of the parties involved. Thank goodness for tools like the Net for

White cheeked eels mispurchase
I have recently bought 2 white cheeked eels and I was wondering, how large
do they actually grow to?
<Do you see them here?:
http://wetwebmedia.com/fwmorayeels.htm>

that they will grow too big for the tank I have.

"Freshwater" Moray Eels 5/3/04
<Hi Dawn, Pufferpunk here>
I recently bought three freshwater moray eels. One of them has died. It was
lying on its side and not eating. The other two seem ok for now. However they
are not eating. What can I do?
<Here is some good info on them: http://fishinthe.net/html/forum/viewtopic.php?t=3627&sid=61704380b037524ca833aa662119a5c1
We have a 70 gallon tank with 4 tiger Oscars, three red Oscars, two peacocks and
two of another kind of fish that I can not for the life of me remember the name
of. We have a few things they can curve under and hide in. but we have no idea
what to do. Any suggestions would be great.
<Wow! With 7 Oscars, you're going to need a much bigger
tank! If I was a sedentary, shy, nearsighted fish like a moray eel,
I'd be afraid to eat too! There is no such thing as a
"freshwater" moray eel. These are not fish for the beginner aquarist.
They are picky, delicate for a moray, and often times never eat. They should nor
be kept with sharp substrates and must have plenty of places to hide. A good
lair can be made by piling driftwood and lace limestone together. Although two
species can live without salt, none of these eels should be considered
freshwater. They all ought to be kept in brackish conditions, with the exception
of Gymnothorax afer, which ideally belongs in a marine
aquarium. ~PP>
Thank you for your time and consideration. Dawn Marie Himlin
Where to get an eel... in France? (03/04/04)
bonjour ,
j'aimerai savoir comment je peyt me procurer la Gymnothorax polyuranodon car je
suis deja en possecion d'une Gymnothorax tile merci d'avance .
<Hi! Ananda here, but I don't read French particularly well... fortunately, I
know a guy from Quebec, who translated this as:
"Hi, I would like to know how I could get the Gymnothorax polyuranodon
because I already have a Gymnothorax tile. Thank you in advance".
My suggestion is that you contact the store where you got the Gymnothorax tile
to see if they can order a Gymnothorax polyuranodon for you. --Ananda>
My eel
HI, I have bought an eel and things have been going great. The eel is lively and is eating.
<Very good, an eel that is eating is a great sign that you will have this eel for years to come.>
The problem is when I bought it at the store it said snowflake eel and I thought it was
until I went to your website. I found a picture in the Freshwater Moray eel section and it looked exactly like my eel.
(I have attached a pic).
<Many freshwater Moray eels are sold under the name Snowflake moray eels. Both of these eels are in the Moray Family. Though a
"freshwater eel", still needs to be kept in a brackish environment (salt added to the aquarium).>
I would like to know how big they grow and some specifications on it.
<Their was no picture attachment to this email, so I'm unable to verify the eel. Since there are many different species of these eels and it's hard to be precise which "Freshwater" eel you have. You can look for the info on
www.fishbase.org. Simply type in the common name and look at the pictures given. They will give you the exact measurements and other information about these amazing creatures.>
I notice that it cant see that well while stalking prey it seems to be using smell more and just lunging
until he gets a fish in his mouth I was wondering if I should be worried about that.
<No, that is a trait of all eels. They go by smell predominately. In fact many eels are nocturnal hunters or they hunt during the early and late daylight hours. Their have quite an impressive olfactory sense.>
Also when I put food in his tank it snaps a lot I think it was because of the fish cause
that's the only time it does that but I wanted to make sure it was alright ( I don't think it was a breathing problem though). Thanks and
I really appreciate you helping me with my questions.
<The eel is alright, and the bad eyesight combined with it's snapping hunting style are the main reason I tell everyone not to feed these animals by hand. They smell food in your hand and can not tell the difference between the food and your finger. Eels have some sharp teeth and will do some damage if they should bite. Keep that in mind.>
Thanks. Allan Wold
<Good luck with the eel. -Magnus>
The new mystery moray eel
Through a trade of an old unused aquarium and my Tiretrack eel I acquired a good
lot of driftwood and a moray eel to hide under it all. It's about 14" and
1" at it's thickest, and when marked at the store it was designated
"Snowflake Moray Eel." That is obviously wrong since the snowflake
moray is exclusively saltwater, and much more it's black and white. I would take
a picture for reference, but he's still hiding under all the wood in a lizard
cave I buried down there and probably wont come out until he's hungry
and ready for food.
<Here at WetWebMedia there is a good deal of info on Moray eels. I
suggest you check out there and see what type you have. There are
many pages of info and you are bound to find something resembling your
"little" guy.
http://www.wetwebmedia.com/morays.htm
http://www.wetwebmedia.com/fwmorayeels.htm >
Having looked up anything referring to snow on fishbase, I came across a
snowflake-patched moray, Gymnothorax niphostigmus, although I'm doubting
it.
<Color variations are one of the reasons why it is hard to classify any thing
out of the Muraenidae family. I myself had one eel that was dark and
very blotched colors sharing a tank with a brightly colored white and yellow
brackish variety of eel... both were of the same species, yet visually they
looked like two completely different eels.>
Looking at the snowflake-patched, it looks like it has eyes that can move
slightly, but mine don't. They are very far forward on the face, and sunken in,
not allowing any range of movement. It's very obvious that it's a moray species
by the gills and face, but I haven't been able to find a match to the color.
I'll try to give the best description possible if it will give you any ideas:
<there are other good resources for searching the identity of your eel. Here
is a good group to start with:
http://saltaquarium.about.com/cs/fweelcareinfo/ >
About 14" long, 1" at tallest length of the body, one solid fin
running along back and body, no spines.
<sounds like something a Moray eel would have>
Mouth is an even arc, teeth weren't seen yet (juvenile?),
<At 14 inches, I would imagine that small teeth should be visible by now.>
eyes are recessed and fixed, and nose has the two pieces of anatomy typical to
moray eels. (forgive my lack of aquatic anatomy) The color is the one thing that
has thrown me off. The body color is roughly the color of a penny. The darker
areas are the color of an old penny, and the randomly ordered spots have
the color of a shiny fresh penny.
<That does sound an awful lot like a Patched Snowflake. If I had
to wager a guess, I would say you are correct in assuming it's a Patched
snowflake.>
According to my friend, the previous owner, it eats frozen krill and small fish,
but ignores anything smaller like blood or Tubifex worms. It's docile and
prefers to be handfed instead of using any feeding rod, which intimidates it.
<I would like to caution you with feeding by hand... Many eels can give you
quite a nasty bite. They don't have the best eyesight in the world,
and when they smell food it's hard for them to discern between your fingers, and
it's food.>
Hopefully someone out there might know of a few possibilities to look into, and I'll
try to coax the thing out of his cave so I can get a good picture of him. Thanks
for the ideas. Robert
<Keep looking around for information. It's hard to figure what
type it is by the description. Also remember that this eels, if it is
a Patched snowflake, will need brackish to Marine water to ensure it doesn't
suffer any skin bacterial infections. -Magnus>
Gymnothorax tile
How's it going,
I have a Gymnothorax tile, he is about 16 inches long
and about 3/4 of an inch in diameter. I was wondering if you could supply me w/
some info. Mainly how long does it get, full grown diameter, disposition and
what measures should be taken if bit. He lives off a diet of live Mollies and
Guppies and raw shrimp (hand feed). I also noticed that it was recommended to
convert him from his brackish water conditions to full salt. If that's the case,
over what period of time and to what specific gravity. Any info you could supply
would be helpful, and educated guesstimates are accepted! Thank you,
Scott Wilgus

Sick eels (12/21/03)
<Hi! Ananda here on the solstice...>
My question is regarding Gymnothorax Tile. I have two eels (1-new\1-2yrs) they
have both been placed in my new 56gal tank, and they are doing terrible, the
older one just hide and eats nothing, while the new one sits crooked and has
recently pooped a white substance.
<The white feces could be a sign of internal parasites. I would suggest
Discomed, sold by Aquatronics, for that problem. The behavior of the
other...could be stress, could be caused by other things. How long have you had
them in this tank? What were the water conditions in the 55 gallon tank,
compared to the tank they were in previously? What else is different between the
two tanks?>
He also seems to have white discolourations on his body, like bruises, but there
is nothing in the tank but 3\4" mono argentus's and the other eel adores
him. The water is 82, salinity is 0.010,
<I hope you mean 1.010; freshwater is 1.000, saltwater is around 1.025.>
do they need extra filtration, are the Mono's edging the eels out?
<How many Monos do you have? (Do realize they get to be dinner-plate size and
will need a much larger tank eventually.) What kind of filtration do you
have?>
Please help me, I love my eels. Also how can I make them eat dead food?
<Try attaching a frozen/thawed version of some of the live food to a string,
moving it around like it's still alive... do read up on how to train lionfish
and marine eels off of live food; the tactics are similar. Good luck. If you are
unable to get them to eat frozen, I'd suggest you consider raising mollies as a
disease-free substitute for store-bought feeders.>
Thanks.

For the snow flake eel?
I am looking in buying a couple for a 75 gallon tank and would like to know what
type of salt to use I don't want it to be a salt water tank but if has to then I
will <for snowflake eels it most definitely should be a salt water tank...I
would go with Instant ocean or Kent marine brand salt> I was going to put
some other brackish fish in there just was wondering about how much a day or
when ever and then what kind?<you need to do research my friend...type
"Snowflake Eels" in the google search engine on the home page of the

- Freshwater Eel Bloating -
Hey all,
I love your site! It has helped me a number of times with my cichlids as well as
just educating me on things that I knew would come up. The problem that I'm
having now is a bit of a mystery to me. I can't seem to find any info of the
subject. I have a Gymnothorax tile
http://www.fishbase.org/Eschmeyer/GeneraSummary.cfm?ID=Gymnothorax
http://www.fishbase.org/Eschmeyer/EschPiscesSummary.cfm?ID=17266
that has been great to watch and keep for about six months. It is now about
12-13 inches long and seemed healthy till about three days ago. The eel is
stopped eating and looked like it had some of the gravel stuck in it's digestive
tract. I noticed some discoloration at the affected area (bruising about an inch
or inch and a half back). It was swimming erratically at the top of the tank
most of the time I was home that day. (weird! usually hiding.) The following day
a little swelling or bloating appeared at the end of the digestive tract
extending about an inch forward. The eel still exhibited the same behavior.
Today, the bloating has extended from the anus to the front of it's abdominal
cavity or whatever (if eels have one? :)). <Sounds like something is backing
up...> I feed the eel mostly ghost shrimp but occasionally a goldfish by
hand. I've tested the water weekly since I started keeping fish and everything
seems to be fine. The temp is 79-80 deg and the pH is 7.6 and I do
keep 1 teaspoon per 5 gal salt in the water. I keep a green terror and a jewel
cichlid (I know, not a good idea) in the same tank and all three have been doing
great until recently. Is there really something stuck or is there some kind of
disease that I'm not finding. <Most likely constipation from one source or
another. Do try some Epsom salts added to the tank - that might help... about
one tsp. per five gallons.> I'm frustrated and worried! Please
help! Thanks for doing what you do! B-Lucky
<Cheers, J -- >
Snowflake Eel FW? 11/03/03
<Pufferpunk here>
can I put a snowflake eel in freshwater, and will it live.

"Freshwater" moray tankmates
<Hi! Ananda here tonight...>
I am going to be setting up a rather large brackish aquarium( probably over 200
gal.)
<Cool!>
and I really wanted to get a freshwater moray eel ( Gymnothorax tile most
likely)
<I do detest inaccurate common names! That particular eel is a brackish fish
when it's young, moving to full saltwater as it ages.>
and I know it is very hard to find suitable tank mates for them. What
would you suggest to fill this aquarium??
<The fish to consider would be others that start out in brackish water and
move to saltwater as they age. Some of the other fish that fall into that
category are scats and Monos. You need to avoid any fish that either spends time
on the bottom of the tank or is small enough to fit into the eel's mouth. Hope
this helps, Ananda.>
Freshwater Eel
Aloha, Pls help me....I have a F/W tank 20 gal about 1 year old...1 African
cichlid 3 1/2", 1 Jack Dempsey 4", 1 Plecostomus 4", and a red
eared slider (turtle), in about 2 days I am transferring them to a 65 gallon,
also I am going to be in the process of changing the tank from F/W to B/W to
accommodate a so called "Freshwater Moray Eel."
<If you change the water to accommodate the eel you will end up harming all
of the others. The Eel will need its own brackish tank. The
African and the Jack will end up having problems as well, the are not
compatible. It is best to keep African Cichlids with other African
Cichlids, they need higher Alkalinity. The turtle is just going to
make a mess no matter where he is. He would be best in a tank of his
own as well, they foul their water too quickly to keep your other fish healthy. Even
a 65 gallon would foul pretty quickly.>
I have a choice from 3 different species...the first is a member of the
Gymnothorax family (the LFS knows not the exact species just that it is a
brackish water Moray), and the other is a Echidna Rhodochilus ...and the other
is said to be a Freshwater Snow Flake Eel (once again the LFS knows not the
species...how surprising huh?) I have followed up on plenty of research and I
know that the Gymnothorax Polyuranodon will not live well at all w/ the Cichlid
and Jack for the water is not the same...but will the Gymnothorax Tile or any
Gymnothorax species for that matter?
<No, same problem, different requirements. fishbase.org is a great
tool for checking the water parameters for different fish.>
And if not what is the best type of F/W-B/W Moray Eel to share a tank with my
Jack & Cichlid without harming any fish...The LFS said to use aquarium Salt
for the change from fresh to brack, And also that the Cichlid and Jack can both
live great in brackish water,
<I would have to disagree with the LFS, maybe check some of the others stores
as well. The African might be able to handle it, but it is really not
recommended.>
is that correct and if so how much to start off DAILY not to shock the fish and
how much max per gallon to accommodate all fish? All of the Eels I am looking to
purchase are 12-14" long...I know I have allot of questions but I just
don't want to harm any fish...hope you can understand...thx for all your help.
<Unless you plan to have a separate tank set up with brackish water I would
go for a different type of Eel, maybe a tire track or something similar. The
African really should be removed as well, they need higher Alk. Best
Regards, Gage>

Sick FW Snowflake Moray Eel (08/01/03)
Good day Mr. Fenner,
<Hi! Ananda here today answering some eel questions...>
Great book buy they way, highly recommended.
<Many thanks, from those who worked on it.>
I purchased a juvenile freshwater snowflake a couple days ago and yesterday
noticed some white crustacean on his nose.
<Ah...presumably you mean "encrustation", i.e., something growing
on his nose?>
Curious I began searching the internet to see of such a symptom - no success. It
appeared to me (in my ignorance) that 1 of a few things could have happened...
either he was attacked by the black shark in the tank, he was digging in the
gravel and scuffed up his nose or he was shedding.
<Hmmm. I rather doubt it was any of those.>
By the time I got home from work, the white crust looking stuff had covered the
left side of his head and covered over his left eye. Obviously
anxious to figure out what was going on, I called the LPS where I purchased the
eel and the gentleman had me bring him back for treatment. He
mentioned something about "cloudy eye" or ich. From what
I've read about ich it didn't seem right. It honestly looks like he
is shedding, looks very much like when land snakes are shedding... probably not
the case but that's how it looks.
<The encrustation doesn't quite sound like ich, but the shedding... could be
a symptom of late-stage ich or perhaps a Costia infection.>
The eel is in a 20 gal tall that has been established for well over a yr,
probably closer to 2 yrs.
<Sounds like a tank that is far too small for an eel.>
The water has been tested and then retested and tested again. All
levels are fine. One adjustment I had to make was to heat the water
up a bit more from where it was to ease the intro from the LPS tank. I
was closer to 78 and the LPS was at 80...
Much appreciate your reply when time permits. Just want to provide
the best possible environment for this little fella.
<Do read up on these guys, starting here: http://wetwebmedia.com/fwmorayeels.htm

Eel lifespan (08/01/03)
<Hi! Ananda here tonight....>
I have a freshwater (brackish actually) eel that I bought 6 years ago and
adapted to live in a Marine tank. I love my little buddy but he's cost me at
least $1000.00, most probably more, in ornamental fish over the past 6 years and
I was curious, how long will he live? if he's only got a couple of years left on
him I'll keep him till he goes to the big tank in the sky. otherwise, I'll find
him a new home w/ a good keeper. its a Gymnothorax polyuranodon to the best of
my knowledge. any help will do.

<Well, you have the oldest individual I've found mention of. Fishbase has no

Snowflake eel
Hey, I just recently purchased a FW Snowflake Eel, (it is a moray). I
was
wondering what I could be feeding it. It is a teeny little thing,
about 8"
and only about as big around as a pen. I have been feeding it guppy

Sick FW Moray eel (04/19/03)
Hello,
<Hello! Ananda here tonight with the brackish fish questions....>
I have two freshwater moray eels and after all of the research I have done I'm
pretty confident they are echidna rhodochilus.
<Yep, I said "brackish fish questions" above, because these fish do
not do well in freshwater over the long term.>
In the last week my eels have been lethargic and do not readily hide during the
day as they usually do. They still have a good weight and color to
them and have a good hiding response when they see me approach the tank. Their
breathing is normal. I recently noticed that the larger of the two eels (the
18" one) has developed what looks to be an internal parasite because he has
about 10 1mm diameter bumps under his skin around his gill area. They
are the same color as him.
<Sounds like an internal parasite to me. Time to put him in the hospital tank
and feed him medicated foods. Start increasing the salinity in the hospital
tank, too. Use marine salt -- mix a quantity of saltwater, agitate it for a day,
then use it as replacement water for water changes on the hospital tank. The
parasites should have difficulty adapting to the saltier water.>
They are in a 30 gallon with two African cichlids. I checked the
ammonia, nitrate, nitrate, and ph and all are in very low levels.
<Whoa -- ammonia and nitrite should be *zero*. If you have any readings of
those, do a water change. Pronto.>
I put aquarium pHarm. doc Wellfish's salt in there (about 10-15% over the
recommended 1 tbsp/5 gal) and keep the water temperature at 78 F for their
normal living conditions. They have plenty of hiding spaces so they
don't stress. I have a power filter and bio wheel also. I
have put them in Melafix for the last few days (I'm only half way through the
treatment) and see no improvement.
<Melafix is not the best thing to use to treat an internal parasite.>
What is this ailment? Is this the right medication to use for this? Is
there a better medicine?
<I would suggest a saltier environment first -- several commercially
available anti-parasite medications include salt as an active ingredient. Then,
if that does not help, something like Metronidazole (AquaZone) in combination
with Pepso food (if the eel will eat it).>
I recently spoke to someone who had this same problem with their eel and they
used Kordon's RidIch and said that they weren't sure if that's what cured it but
it went away in about 2 days. I'm a little leery about using this on my eels so
I went with Melafix instead. Would RidIch be okay or better?
<Rid Ich is reported to be formalin and malachite green, both of which are
more useful for skin parasites.>
Is there a good site on the diseases these fish are prone to? Please help I've
had them for a year and do not want to lose them.

<The eels will need to be in a brackish tank for their long-term health.

Freshwater Moray Eel
Can you answer a question about this type of eel?
<Yes we can.>
She had a disguised tube that she hides in, she's been in there for 3 days now,
and lays on her side most of the time. Is this normal?
<Hiding is normal, laying on the side is not great. Start by
getting your water tested, send us the results as well as your systems
specifications, and what you have been feeding him/her. We should be
able to get to the bottom of this. This fella may be better suited in
brackish water. -Gage>
The laying on the side may have been misinterpreted. I had these very
same "freshwater" morays (3 to be exact) that I kept in a fish-only
saltwater setup (they were beautiful once acclimated, deep purple with gold
spangling. This may have been due to them eating Hikari Color
Enhancing Pellets for cichlids as their diet.). At least in my very
limited experience with morays, if they have any length to them, often the body
and tail lay flat on their side due to the flatness (more football shaped) of
their bodies. It is hard to balance a football on end, but laying it
on its side is easy. Of course, if the entire body is on its side
(head and all) then there is a serious problem.
By the way, these guys are aggressive feeders. I had a Volitans
lionfish and a niger trigger in the same tank, and one night I woke up to some
violent splashing. I turned on the light and they were biting the
lionfish and tying themselves in a knot and pulling their head through the knot,
bring a piece of flesh with them. They tried to do this to the
trigger also, but only managed to skin him. Both lionfish and trigger
died. I took them to a LFS the next day.

<Thanks for the input Jason. I think I would be afraid to sleep in
the same room with those bad boys. -Gage>
Re: Freshwater Moray Eel
I've only had her for 3 days. I know she hasn't eatin anything
yet. How long can they go w/o eating?
<most likely a few weeks>
She is in a 75 gallon tank: the water temp is 83 and the water is slightly
brackish. I thought maybe it was just the transfer from the store to
here, but I'm not sure how long it would take her to adjust...
<Could be from the transfer, very common with eels. See if you can
verify the species, some need more salt than others. Try searching on
WetWebMedia and also fishbase.org. -Gage>

Re: Fresh water eel?
Hello,
One of my friends recently (he left the state) gave me what he called a
freshwater snowflake eel. I looked up stuff online to find out what
it
needs to live and I found that it is probably a brackish fish but I have
been keeping it in fresh water. I don't know how to identify it or switch to
brackish water in my tank. He is currently about 5-6 inches long and in a 5
gallon tank all by himself and I haven't gotten him to eat yet. I
think he
is either Echidna rhodochilus or Gymnothorax polyuranodon. what should I do
to find out what it is and how to keep it from dieing? Yours truly
Ben P. THANX!

Re: White Cheek Moray Eel
I hope you have time to respond. I have purchased a White Cheek Moray Eel.
It is 10" in length. I have it in brackish water at this time. I also have
a
Spotted Peacock Eel in the same tank. I know the White Cheek will at some
point need pure marine water. The people at the pet shop knew very little
about this species. What water temp., when to change to marine water, its
mature length?
<Please see here: http://www.wetwebmedia.com/FWSubWebIndex/fwmorayeels.htm>
I am looking at a Snowflake Eel to be a tank companion to the
White Cheek (12" in length) but they already have it in marine water. If,
at
any point do I get the Snowflake?

Re: Echidna rhodochilus
What do you think the best type of food is for this kind of eel?

A LFS blunder? Not so FW eel
Bob,
I have been writing you asking you questions about the wrong species. What I
had been told was a GYMNOTHORAX POLYURANODON, turns out to be a ECHIDNA
RHODOCHILUS .
I found an exact description on fish base, my question is these eels are
more in need of a brackish if not full marine water setup than the gymn poly
right ? If so what is the easiest way for me to make a conversion to keep it
healthy until I can get a new set up going if there is one? But on a side
note all the info I got from you on the Gymnothorax polyuranodon has me in
great shape for when I do get one.
Once again
Thanks for all your help!

Eels on the skids
Bob,
I've got problems one of my eels died.
I did not see it but my wife told me that the one who died, had been listing
or laying on either side.
The eel showed no signs of ich, slime, or any obvious illness. The larger of
the 2 (the only one left) seems to be doing the same thing ,
but not constantly it also is still swimming around allot.
What could it be?
Dave Siecinski
<Whoa! What species are these? Marine, fresh, brackish? Tell us about your
set-up, maintenance, history... Bob Fenner>
FW Moray eel illness
Sorry I got a little ahead. GYMNOTHORAX POLYURANODON, IN A 7.8 PH freshwater
tank sand bottom , temp between 76-78F. I just did a water change yesterday
about 1/2 the tank , added about 1 Tbs uniodized salt (10 gal tank). Like I
said the eel is listing or laying on its side, it shows no obvious signs of
illness. (ich, slime, or abnormal markings) Got any ideas?
Thanks
Dave
<How long have you had this fish? What is it eating? Most don't make it
through the first month... likely due to trauma, the stress of collection,
shipping. Bob Fenner>
Bichirs and FW eels?
I've been attempting to feed it krill, prawn, (both frozen) ghost shrimp
&
feeder guppies the 2 Bichirs I have in with it usually hit the krill & prawn
and although I have not seen it the feeder guppies I had in there got eaten
during the night. I've had the eel and the Bichirs for about 2-3 weeks.
<Mmm, these two types of fishes should be kept in separate "types"
of water. You can read about them on WetWebMedia.com or fishbase.org... I
suspect that your problem lies with the incompatibility here. Bob Fenner>
Gymnothorax polyuranodon, freshwater et al. moray
Other sites say that these guys are strictly freshwater , but some sites
agree with the info I got from WWM. (very confusing) Now I'm more apt to
believe you and your crews advice due to the fact my best friend who use to
be very heavily involved in the hobby (while not being an authority on eels)
had said things (prior to writing to you )that reading your responses to
other questions went right along with his best educated statement. If I
should change the salinity of the tank as the eels mature, how do I no when
to up the salt without waiting too long or making the transitions too
prematurely?
<Do take a look at the "stock" listing re this species on
fishbase.org. It is found in freshwater habitats, as WELL as marine, brackish. I
encourage people to at least consider some salt in its water... on the basis of
their being a chance that their source water is acidic, has little buffering
capacity. How to put this... all else being equal, it's better to treat
Gymnothorax polyuranodon as a brackish water species, though it can by all
accounts be maintained long-term in freshwater (that is hard and alkaline).
Please see our brackish water section:
http://www.wetwebmedia.com/BrackishSubWebIndex/BrackishSubWebIndex.htm
re issues like water preparation.

FW Moray ID
Hi,
I recently picked up 2 freshwater morays at my LFS. They seem very honest
about what they do and do not have info on. They have told me the eels are
GYMNOTHORAX POLYURANODON the common name was white cheeked moray. No
photos
I have seen yet of that type or any fresh/salt water moray match what
these
2 look like. They look to be in good health (no weight loss or anything
unusual ) actually they seem to have gotten bigger in the short time I've
had them. I have a couple of photos maybe you could help me track them to
an
exact species.
THANK YOU

Re: sick freshwater Moray eel
Thank you so much for your speedy reply, it was very much appreciated.

Salinity
hey bob, what should the salinity be in a freshwater moray tank?? is a
tablespoon per 5 gallons a good idea or should it be higher??
<Depends on the species... there are some general guidelines for the fishes
called FW Morays, brackish in general posted on WetWebMedia.com
Please use the Indices or the Google Search tool there. Bob Fenner>
Jiwan..
Freshwater moray eel??
Hey, well thanks everyone BOB, CRAIG. That was really helpful.
<Hi Jiwan...well, apparently not helpful enough I'm afraid...>
Yesterday I ran into something at my LFS. It's called a freshwater moray eel
(GYMNOTHORAX POLYURANODON). Grows to around 28". He's around 14-15" at
the moment. I purchased it. Do you think if this is a good idea??
<I do NOT think this is a good idea at all and will not work. You are trying
to combine Brackish MARINE Eels from the Indo Pacific with African Cichlids from
Lake Tanganyika and Lake Malawi in Africa. They do not live in the same
environment. The higher pH African Cichlids require is NOT the same as salinity.
Not to mention these eels grow to three feet long *if* they live. The following
is by Bob Fenner from WetWebMedia.com. :"Gymnothorax polyuranodon (Bleeker
1853), a "Freshwater Moray". Indo-Pacific; Sri Lanka to Fiji, down to
Australia. To about three feet in length... if it lives... most do not... this
is a brackish to marine/estuarine species. Best considered brackish." You
do not have a brackish marine system. Please take the eel back, it is doomed as
are the Cichlids in salt water. Marine salt and aquarium salt are not the
same.>
The guy at LFS told me to put in about 1 tablespoon per 5 gallons of salt in the
tank to make these guys comfortable. I already put that much in my tank anyway
cuz I have African cichlids in there. I feed him 2 shrimp yesterday, I mean I
tried to. He didn't eat but when the lights went out he was swimming all over
the place biting in the gravel to look for food. How should I go about feeding
these guys?? And where can I get hold of a feeding stick??. And honestly is this
going to work?? Jiwan
<No. It will not work. It is absolutely vital that livestock purchases be
well thought out and researched. Please take some time to find out about some
animals that might interest you, research their living conditions thoroughly,
and then supply the proper conditions for them to thrive in captivity. Those who
fail to educate themselves are at the mercy of the salespeople at their local
fish store, who may not have the interests of the customer or animals in mind.
When you take the eel back, buy a good book on African cichlids and change your
water to match the water your fish come from, which is fresh water, high pH and
alkalinity, not brackish/marine. There is lots of information on WetWebMedia.com
on all of these fish and eels, please go there and enter the fish of interest in
the google search. Hope this helps. Craig>
Freshwater Moray eel?
Hi Bob
<cheers>
I've had my freshwater Moray eel for a few months now, but it really looks like
he's dying and I don't know why. I'm hoping you could please help me before it's
too late!
<the first step is to ID your species and verify how "freshwater"
it is if at all. Many species sold as such are brackish at best and need more
saline water as they mature. Some stay brackish and others really are
freshwater. Most FW eel sold as "morays" however need serious salt and
attention to salinity. A tragic death for many. Please look through fishbase.org
to find yours and through our archives on WetWebMedia.com beginning here (be
sure to explore links/FAQs at the top):
http://www.wetwebmedia.com/FWSubWebIndex/fwmorayeels.htm >
He is breathing very rapidly and gaping his mouth constantly. He's blue around
the throat area and lies on his back for a while, before turning himself upright
again.
<ughh... commonly occurs from incorrect salinity. Check ID of this species...
resist changing SG drastically yet... get a hydrometer if you don't already have
one to measure salinity and add some extra aeration to the water please>
I did a partial water change a few days ago, and he's been looking sick since
then. I throw shrimp and baby clams in than tank as well as pellets. The only
food we have seen him eat is live glass shrimp. I read somewhere that they can
go for months without food, is that true?
<possible yes>
I added more salt to the water last night. What else can I do?
<research my friend>
Many thanks Nico

Eel question
Hey Bob, my names Joel. I'm up in college right now, and I was given a fish
tank (20 gallon freshwater). I went to the local aquatic store looking for a
puffer fish, and walked out with an eel.
<Ughhh... not another so-called FW moray eel>
They told me it was a freshwater snowflake,
<that story will likely turn out to be a big pile of crap>
and it preferred brackish water, but would live fine in freshwater.
<correction... a big steaming pile of monkey crap>
I read a couple things online that say snowflake's won't live long in
freshwater,
<Amen and pass the ammunition! Keep reading/researching my brother. You are
almost a perfect aquarist/educated consumer. I say "almost" perfect
because you just might end up killing an eel that you bought and brought home
before actually knowing its needs for survival <G>>
and I have a discus in my tank as well, so putting salt in the water would kill
the discus.
<these are two completely incompatible fishes... yes. No salt for the discus
and likely plenty for the eel. Before we can say for sure... you must ID the
eel. Use fishbase.org and look through our archives beginning here:
http://www.wetwebmedia.com/FWSubWebIndex/fwmorayeels.htm >
Do you have any suggestions for me?
<yep... you need a separate tank for the eels and discus. One likes soft
acidic water and the other likes salted alkaline water and a compromise of the
two would be cruel if even possible>
Should I put a certain amount of salt water in my tank (5-10 gallons) and give
the discus to the fish store (they said they would take it if I wanted to give
it up) or will the eel be fine in the freshwater?
<good idea, bud. If you really like the eel... do take the discus back ASAP
and keep the eel brackish>
Also, one of the sites I looked at (it may have been yours) recommended a 50
gallon tank for the eel,
<correct for most if not all>
I have 20 and I was told it was large enough. What do you think?
<I think the LFS lied or were ignorant (not knowing)... you will need a
bigger thank for the eel in the future, my friend>
Thanks for your time. Sincerely, Joel

an educated consumer. It is the best weapon you have against misinformation.

Re: African cichlids and eels??
hey bob,
<Gage here.>
thanks that was really helpful.. but u didn't answer one of my questions.. would
the fire eel eat the other fish seeing that it can get to 3 feet long??
<No, the fish that you are keeping are pretty dang tough, I would worry more
about the eel.>
and also if not the fire eel r there any other eels that I could keep in this
type of a setup???.. my frontosa is pretty passive.. the only one I am concerned
with is my Malawi blue dolphin he is pretty aggressive..
Jiwan
<I would not add any eels to this set up, I would pick one lake and go with
it. Your Frontosa is from Lake Tanganyika, and the blue dolphin is from Malawi.
This will not work in the long run, it is best to stick with cichlids from the
same lake, and possibly some catfish. How big is your tank, the Frontosa can
reach 13in. Best Regards, Gage>
African cichlids and eel??
hey bob,
<Hi Jiwan, Craig here>
Thanks very much. So if a fire eel is a bad idea would a freshwater moray eel be
a better option, seeing that they like salt in their water and African cichlids
live in alkaline conditions and I do have salt in my tank. The salinity is
1.005. Would a FW moray eel work?? Do I have to worry about them eating the
other fish in the tank??
Jiwan
<"Freshwater" Morays are not really freshwater residents but are
really brackish residents that require 1.005-1.010 SG salt water. African
Cichlids are freshwater fish requiring a higher pH and hardness but they could
not survive brackish conditions. You would not like the results regardless.
Please do research stocking options on WetWebMedia.com. Craig>
Snowflake Eel
Mr. Fenner,
Hi, my name is Lisa, and my husband and I own a Snowflake Eel.
<Likely Gymnothorax polyuranodon>
We've had him for about 3 months now in a 10 gallon tank with three black fin sharks.
<The seawater/brackish ariid catfish>
Recently we bought a 29 gallon tank and put them all in there. The black finned sharks seem to be doing all right, however our Eel does
not. I was hoping you would be able to help us determine if there is something that we are doing that might be harming him. The tank is a
brackish tank. I'm not sure about the specifics of how much salt etc. because my husband does all that. The eel's nose is turning white,
almost like he bumped it on something, and he used to be rust colored with white spots, but now he looks pale and we can barely see his spots.
If you have any information that would be of use, could you please let me know. Thank you.
Lisa Meyer
<Mmm, the move to larger quarters was a very good idea... as the catfish/sharks do get quite large (please read here: http://www.wetwebmedia.com/ariidcats.htm) as can the eel (here: http://www.wetwebmedia.com/FWSubWebIndex/fwmorayeels.htm). You may need to move these two types of fishes apart... as the eel is a far less aggressive feeder than the "sharks"... otherwise, do check and adjust your specific gravity (saltiness) to about 1.010 over a period of a week or two, try some other foods (ghost, glass shrimp). If the eel does not improve (it does have a pipe or such to hide in?) I would definitely separate it to another system. Bob Fenner>
Re: Snowflake Eel
(do check and adjust your specific gravity (saltiness) to about 1.010 over a period of a week or two)
How would we do this?

Gymnothorax polyuranodon
Hey Bob,
I know you all over there in Wet Web Media will pretty much tip over
after reading this email.
<A tall challenge. A few of us are built like those old clown punch bags and just "pop up" when pushed over>
I have 4 Gymnothorax polyuranodon in a 29 Gallon tank. The largest
being 24 inches long and about as a thick as a quarter. The smallest
being about 14 inches long and as thick as a pencil. I have had these
particular Gymnothorax polyuranodon for almost a year. I rarely change
the water. When I do, I just pour tap water directly into it. Mind you,
I pretty much unknowingly have gone against ALL instructions and
"educational" advice that is located here at WetWebMedia.com. or
anywhere else that I have recently have found on the Internet.
I feed them little crabs, ghost shrimp or Krill that I get at the local
pet store or PetSmart. Their housing consists of PVC 1" tubing that
line and cross the bottom of the tank under the gravel numerous times.
About 10 feet of PVC tubing not counting the "elbows" and "T's". The
water temperature can range from almost 98 degrees on a warm day to 75
on a cold day. I have never check the Ph. I have never really done much
to it other then add food. Although, I do have a Pro-Quatics 2400
filter, it does 125GPH. It isn't a great filter but it does the job and
is very quiet. I do a filter media change once a month. The lighting is
nothing special either, a black light and cool white GE florescent bulb.
My girlfriend calls it a hostile tank because there is nothing that
isn't cute, except the snail. Whom is never bothered and just continues
to grow like crazy. Although, I have never experienced a "feeding"
problem or a health problem.
<Sounds like you've been successful>
The reason I am writing to you now is this: One of the Gymnothorax
polyuranodon
that has never been to bright in colour. Actually it has no colour other
then dark "brownish" with a few typical markings of the species. I
believe this is a female.
<Maybe>
I have no scientific expertise in this area, nor do I claim to be any
sort of a hobbyist auquariumist- However, due to the wriggling and
intertwining of the other Gymnothorax polyuranodon with this
particular one as of late. Recently, it has been becoming "fat". It is
not really fat, per se. It is more like "above average thick".
I have read pretty much EVERYTHING that is on the Internet regarding
this species. Well, what little there is. And the conclusion of data
supplied by experts is that there is very little known and general
consensus is that it is not even known how Gymnothorax polyuranodon
reproduce.
<As far as I'm aware there isn't much that is recorded, known... you may be the person with the most knowledge>
I have no idea either, I would love to say " Yea, the little bugger ate
some really big (fill in name of thing)". But. there is nothing in that
tank that would do this. And nothing that is missing out of the
ordinary. So, who knows. I guess if this Gymnothorax polyuranodon gives
birth and I have a million of these things in the next month then we
will know for a fact it was fertilized. Wouldn't that be ironic.
<Mmm, more likely to be a "real mess". The true eels produce a great many eggs... and sperm... these are released in the water... and a good deal of time (look up and read the story of the best-documented group, the Anquillids) as pelagic larvae...>
I apologize for not being a "be all you can be " aquarium-ist. I do plan
to institute some changes in the tank and so on --upon reading all the
material this evening.
<Good for you, and them>
Please do not release my email address or use of my name other then my
first name thanks -- if you choose to use it ..
G'day..
<We don't unless folks insist on actually doing so... one never knows. Hopeful though that someone will read your input, chime in with useful information as well. Please keep an eye on the freshwater moray FAQs (http://www.wetwebmedia.com/FWSubWebIndex/fwmorayfaqs.htm) and dailies. Bob Fenner>
Moray Eel
HI..!
I used to have a Gymnothorax polyuranodon until yesterday, it was ok swimming and eating well the day before I found it upside down, move it and swam as always but yesterday was again upside down but when touched it just rolled several times, but never went back to
swim as usually, a few hours later died.
I don't know why, I have 5 tiger barbs, 1stingray (orbignyi), 1 plecostomus, I
change 25% water two times a week, could you help me in discover what cause my eel to die.?

So-called Freshwater Snowflake eel
Mr. Robert Fenner,
<Anthony Calfo, in your service, my friend>
I have a Snowflake Eel that's been swimming on its side erratically from one end of the tank to the other and sometimes resting upside down. I've noticed he's been breathing very rapidly, too. He's about 28" long and lives in a 65 gallon tank, along with seven 2.5" African
Cichlids (variety) and a 22" white cheek eel.
<the first and most likely problem with your eel is that it is suffering from the extended captivity in freshwater. These so-called "freshwater eels" are only
comfortable in freshwater at best as juveniles. As they mature they migrate out to brackish water and some eventually to the sea. This is a common question and problem. The size of your eel and rapid gilling is a giveaway. Do buy a hydrometer and begin a adding sea salt slowly to bring the salinity up by .002 daily (not too fast!) until you reach at least normal brackish water of 1.010 within two weeks. Since you have Africans in the main display... I assume/hope that you are already adding a little salty, eh?>
I also keep the feeder gold fish, about a dozen medium size gold fish,
<really...goldfish are an inadequate food item for crustacean feeding eels. Predators forced to feed on such deficient prey often die of complications prematurely. The aquarists often doesn't realize it
because the fish seems to be "fine" eating them for a couple of years (but still doesn't reach a full lifespan). Be sure to mix up the diet with great variety of shell-on creatures (krill, plankton, shrimp, crayfish, etc)>
in a floating container inside the 65 gallon tank. I changed 20% of the water last Tuesday and he's been eating 2-4 Gold Fishes every other day. I've noticed this change of behavior Saturday evening. Right now I have him isolated in a 20 gallon tank with seven small gold fish (feeder fish). He's not very responsive and tends to lay on its side, sometimes. His breathing tends to speed up at times (average about 49-50 breaths per minute) and slows down (30-32 breaths per minute). I'm a little worried about him. I've had him for about 3 years and I about him when he was 17" long.
Do you know what might be wrong? I've enclosed a picture of him in the sick tank.
<yes... please add some salt promptly as prescribed above. Anthony>

Two questions
First of all thanks for your last advice and fast response, I will get the PH and nitrite tests.
1) I have a Gymnothorax polyuranodon (freshwater eel) and some times he changes color to a pale one but just happened twice during a
month and later he has its original color, is this normal or what could be happening? is eating well, as I see during everyday observation is quite good.
<This is normal... seems to have more to do with "mood" than water quality, other external influences... Not necessarily an indication of trouble>
2) I will get a freshwater stingray soon but I can't find written thinks online about injuries caused by the sting and
envenomation, what should I do in case of envenomation or being touch by it sting ( accidentally, of course I will take care of this everyday).
<Please take a read through the Freshwater Stingray article:

and we'll be chatting. Bob Fenner>

Freshwater eel? Not in this case?
hello sir
<Greetings, Brian. Anthony Calfo in your service>
I recently purchased a snowflake eel and I'm getting worried about it
is pale colored and it like to lie on its side, gasping for air it seems, I have 3
African cichlids, a tiger Botia, and a blue crawfish, the eel is about 1 foot long they all live in a 20 high he
hasn't looked healthy and I was wondering if you could give me your opinion of what it is
I need to do. thank you for you time. Brian Dillon
<Brian...your eel is most likely a brackish species. Fortunately, it's tankmates will tolerate and even appreciate some aquarium salt. Add 1 tablespoon per five gallons for starters and only replace it at that dose when you do water changes (not evaporation top off). And look for a picture on the Web (this site and
www.fishbase.org) for a picture to identify the species so that we can better help you. Let us know if your eel breathers easier with the salt in the water. Also, test your water quality for any low pH, high ammonia, etc>
Eel food..?
Hi..!
searching on your site I found my eel is just the same as: Gymnothorax polyuranodon .
<excellent, Carlos... but that is a good stretch from the tile eel species mentioned in your first e-mail. The feeding advice stays the same... but did you buy the eel in fresh or saltwater. If saltwater, disregard the history mentioned in the last e-mail. Best of luck to you, Anthony>
Thanks.!

Freshwater Eel?
Hi..!
<Hi, Carlos... Anthony Calfo in your service>
A few days ago I got an eel, searching at the web found is just one alike and is called lycodontis tile eel, is just exactly the same I have but I'm not sure if it is a snowflake eel (?).
<no sir... you have a variegated "freshwater eel", which favors brackish water and if kept in freshwater may be stressed not to feed... but not a snowflake moray eel>
This is now 6 inches, small but healthy as I think, it open its mouth sometimes when quite in a place and moves greatly but feeding is kind of concern, since 4 days ago never seen it eating, I tried freeze dried blood worms,
<good food, but not likely to be taken>
fish flakes ( as pet shop owner recommended) a
<that person needs a good book... the only way that eel is going to eat flakes is with a slingshot>
and now after more research I set a toothpick with beef heart with just small bites on it but not sure if they were from the eel.
<hmmm... perhaps>
What do you recommend about this situation?
<try crustaceans (live and frozen)... krill (FD and Frozen maybe)... live ghost/grass shrimp very good>
my eel is moving and breathing as usual so I think is healthy, color, eyes and dorsal fin ( from head to tail) is ok.
<excellent>
What kind of eel is this one.? probably it just eat live fish and need to try. Best regards.
<live fish not necessary, I believe. keep us posted, Anthony>
Re: ALL CAP.S and stocking cichlids and eels
what's wrong with all capitol letters? is this better?
<Yes, thank you. Much easier to read... an aspect of "netiquette"... rules of polite society>
I'm not shouting. ok.
(lol)
can I put a freshwater eel in a 55 gallon tank with a red devil and a green
terror.?
<Mmm, not really a good idea... "the" freshwater eels are too slow, blind to compete with such "go-getter" cichlids. Please read here:

Freshwater morays
Hi Bob,
I have been reading the FAQ on freshwater moray eels and was wondering if you
could help me out with a query of mine.
A friend of mine recently acquired 3 freshwater morays directly from a
wholesaler. He was informed that they were a freshwater species and that the
specimens were actually bred in captivity in freshwater.
<Really? Hmm, have just this last week finished spiffing up this se |
