I find this very interesting, I have had 4 fire eels over the past 3 years , and have lost 3 out of the 4 to finding a way out of completely covered tanks. And when I say completely covered, I mean what I literally thought there was no way out. Oh yea, if there is no way out, they will find one. The one I have left was the first one I bought, which strangely enough he also got out of the tank, and I found him dried up and stuck to the carpet, but to my astonishment still barely breathing. I held his dried body with hair and carpet fibers stuck to it over a bubbler for 2 hours, and here it is 3 years later and he eats jumbo bloodworms out of my hand every day. Can't imagine anything going a year without food, this story is baffling, but so is a dried up eel stuck to the carpet who is still alive and thriving today.
Fair point. Well, I hope to report at some point that I observed the lil bugger eat something.
