I owned one for about two weeks they are beautiful eels. Unfortunately the eel jumped out of my tank and died, so make sure you have a cover over your tank. They like places to hide as well either lots of rock or some people use PVC
pipe buried under the sand. I have heard they can be picky eaters but the one I had was eating frozen krill with no problem. I currently have a snow flake eel and he is a amazing eel too. One thing to caution when owning eels make sure they can't escape your tank I have lost two eels that way.
