I have one and have found it to be an incredibly easy fish to keep. They will eat everything you put in. He mostly hosts in a toadstool leather, but also hosts in a plate coral (at night). The only thing to consider is that they are supposed to be one of the more agressive clowns when they get larger. This is significant as they are also one of the largest clowns (to 6 inches). I added my GSM last since it is in a tank with a yellow-tail damsel (clowns are a type of damsel fish) and 2 false percs. He's been in there for about 8 months now and is still on the bottom of the pecking order. I have no problems with the different clowns fighting, by the way. The damsel picks on the GSM a bit though as they have staked neighboring territories.
