look at his body, make sure there are no white spots or anything. if there are white spots, get some marine ich medicine like copper (i think thatll do the trick). also, did you check to see if he was eating at the store you bought him at? if he wasnt or was acting sort of weird there, not swimming away when you approached, etc, then he might have been sick from the start. try using some live food to get him to eat, and with eating he might get better. it could also just be a stress issue with being introduced too fast, etc.
