I do hope the fire mouth settles down, but if not he will go back to the fish store. the problem in this town is there is no fish we can choose from, the store is so small, and he does not order often enough. so we are stuck with poor choices.
How long has the tank been set up? and did you cycle it?
The firemouth is not going to "settle down" he will have to go back to the LFS or your other fish will be harrassed to death. Or you could always get another tank for it...
And see if you can find out what kind of suckerfish you have, because there are many (like CAE) that will not work out.
