'freshwater' Moray Eels

[GobyMaster]

Okay, I am thinking of transferring from Freshwater to Brackish Water, and there's one fish in specific that I want in my tank, but can someone give me the care info about this fish here:

I found one at a locally owned fish store in town, and it's really cool. I now that morays don't more around that much, but is it different from marine and brackish morays, for instants, would a freshwater moray be more like a bichir when it comes to how active it would be, or would it be like marine morays where they stay in caves nearly all the time?
Also, does anyone know how large a freshwater moray can get? I have an empty 36 sitting at home which I want to use for my brackish, but would that be big enough?

Also, tankmate wise, anybody know of any good ideas??
I want to put another Marbled Sand Goby in there, but I'm not sure if the Goby will eat the eel. If that doesn't work out, how about those shark catfish you see at pet stores? I know those guys can get pretty big, but I have a 125 I can put them in if they get too big.
If there already has been a care sheet for them made here, sorry, I'm new, but I'll appreciate all the help I can get for fish I can put in this tank.

I have 3 of the common "freshwater" morays (Gymnothorax tile) in my tank which are all between 15 and 20 inches long, i previously had a larger specimin which measured 27 inches from nose to tail when she died so these fish do get pretty big. As for activity and behaviour they are very similar to the marine morays, for the most part they just sit in the rocks with their head poking out but they do become active and swim about when they are feeding.

The 36 will be ok for a starter tank and could even help to begin with as they can be difficult to get feeding and usually require target feeding using tongs to get them onto dead foods but they grow exceptionally fast once they start to eat properly and will need the 125 within a few months.

These fish are intollerent of excess heat and often perish if the tank becomes too warm over the summer period, females in particular appear to be triggered into breeding condition and then die from being egg bound when they are unable to spawn, this has been the fate of 4 previous morays of 3 species i have kept. If the temperature in your tank is likely to exceed around 27c then the installation of a cooler unit is highly recomended.

CFC, have yours ever attacked or disembowled any of your other fish? Horror stories about this puts me off one...

The largest moray i had which was a Gymnothorax afer and was in excess of 30 inches took a fillet off of the side of a shark catfish but that is the only incident i've had with morays of any species attacking or eating other fish, unlike my toad/stone fish which has eaten 3 puffers a couple of small morays and even a mono.
