How can I get my Rev Devil to come out ?

[Joeybsmooth]

All he does is stay in his house all day and doesn't do anything. It is nothing in the tank that would bother him.

Normally I would suggest some dither fish, but I don't think that any other fish would be safe.

How about if I put another aggressive fish in. (I don't want them to fight ) but another top dog might make him more active.

Tank size and stock?

Take away his house, remove all decor and force him to feel comfortable in the tank.

I agree with HUKIT on this. If he can never see whos feeding and whats around him he will never know its safe.
