I've always wanted a Fire Eel. The reason I can never have one is because my wife would never allow it. It reminds her to much of a snake. I would have to have a secret house with a secret fish tank and a secret Fire Eel. lol
I had the same problem. My wife didn't like eels because they look like snakes. I bought a small TT eel, and she always associated it with a worm (always called him "wormy"). As he grew, she was used to him, so looking like a snake never became a problem.
