Clowns near death...

[ouchthathu]

About 2 weeks ago I purchased 2 Percs (one wild, one aquacultured). Near the end of last week both clowns stop feeding and began swimming near the top of the tank on thier sides.
Monday the wild perc died.
It's Thursday and the tank raised perc still hasn't fed and is hanging near the top of the tank and is obviously stressed (fading colors, rapid gill movement etc.).
Is there anything I can do to save this clown? I've tried cyclopese, brine shrimp (live and frozen), mysis, flake, and pellet... he won't touch any of it.
All the other fish in the tank are fine and aren't exhibiting any problems (royal gramma, 2 blue damsels, 1 lawnmower blenny, 1 Coral Banded Shrimp, tons of snails and hermits).

how did you acclimate?
what are water parameters?

Could be an infection outbreak but cant say for sure. Thats why its good to quarantine new fish. I would recommend removing the clown and putting it into a quarantine tank and keep a close watch on it. If its affected by ich or something you would have to take the appropriate measure to erradicate it. If its something infectious, it could spread to the other fish depending on how good their immune system is. Just to be on the safe side I would soak the food for the other fish with a garlic extract. Then again it all depends on the exact problem of which I cant be sure.

how did you acclimate?
3hr drip method.
what are water parameters?
0 Amonia, 0 Nitrite, less than 10 Nitrate (too low to register). 8.3 PH temp steady at 80.
Could be an infection outbreak but cant say for sure.
It's not affecting anyone else (yet) and there are no signs of infection, just stress. I'm not real sure he's going to make it another 24hrs at this point, if I move him to quarantine, what would I treat him with?

If its just stress then I dont know what treatment is possible. In which case its a wait and watch game. Keep the light levels a little low in the quarantine tank. Hopefully, someone will come with some other advice here....But it might not be just stress...might just be that the other fishes have better immunity right now since they are old residents.

Thanks,,, but it's to late now. He was "fin-up" and not breathing when I checked on him a few minutes ago. I'll have to watch a while and make sure it was just him and it doesn't affect the others in the tank. A post-mortem indicates nothing amiss (no ick, no slime, no aggravated areas, no missing scales). Just skin and bones thin and a loss of color.
