I had one of these in a 100 gallon tank for about two years. It is a great fish, but don't keep it with anything small. It will eat any Damsels in the tank within days. It ultimately died when it got put in a tank with a Tesselata eel which is the far larger and more aggressive species. It managed to stay a while with this eel, but was eaten in the end.

I have had one of these for the past two years and it is awesome. I feed him Formula One which really brings out his colors. When I bring his food to the tank he comes right up to the top like he's begging. This is the hardiest fish I have ever owned. About a year ago I had a bad ammonia spike and he was the only fish to survive. These are great fish!
