I work at a pet store with this BEAUTIFUL green wolf eel. I would love to get him. He's been there for a while, so hopefully, he's not going anywhere soon. I'd like to get a 37 or 47 gallon column tank. I've read they have bred in as small as 30 gallon. Live Aquaria says he needs a 50 gallon minimum.

So would he be happy enough in a 37 or 47 gallon column tank?
Also, if he would be happy in a 37 or 47 gallon column tank, who would be compatible for that size tank?
This is what he looks like:

Thanks!
