Is my clown sick?

I posted this in the fish disease forum without getting more than one vague response so here it is...

Is my clown sick?
I added two true perc clowns to my newly cycled tank four days ago. I watched both of these fish eat at the LFS. The tank is a 75g w/29g sump/fuge. First about the fish then my water. One of the fish eats great. The other fish does not eat at all. I have fead flake, pellets, frozen mysis shrimp, and frozen brine shrimp. The fish that is eating only turned down the flake. I tried a little garlic with mysis shrimp and that did not help either. The fish looks healthy and does swim around a little but she is not active as the other clown. Does this fish have a disease or parasite of some sort? Like I said earlier I cannot see anything wrong with the fish.

thats what happend to my fish.. i have one now thats about 2" who always eats but not flakes.. and i added another smaller one to keep her company. he ate some pellets the first day or two.. then stopped and nothing looked wrong with him. the night before he died i noticed his colors were pale. then next morning.. well flush..
the only thing i noticed is that my larger fish when i added the smaller one got aggressive eating... chasing all the food. maybe it scared the poor guy not to eat?

try giving live brine, is it swimming/acting normal? if it is swimming and active I think it will pull through, but if it is lethargic all the time I wuldnt keep my hopes up. anyway try the live brine. this stuff is crack to most fish and they cant turn it down
