I have had this eel for over two years in a very stable 75 gallon tank which has had no new additions for at least a year. About three months ago, a hump started to appear on his back and has progressed to a very large hump and what looks like "guts" sticking out the other side. I keep expecting him to die, but he eats and behaves normally. He just looks horrible! Please see pictures.
Does anyone have any ideas what is wrong? Is there anything I can do to help the little guy?
Thank you for your help!
Daphne
