Looks like there is bacteria floating in your water, the disease looks like brookynella (spelling?). Have you make water changes? Becareful when adding medications to the tank, may have adverse effect on the corals.

I suggest you do a major water change or more often (every few days)in smaller volumes and leave it for a month or so before adding new fishes.

If it is brooklynella, you need to use formalin to treat your fish, is it a clown fish? Chech with your LFS for the use for formalin and it's dosage if it is brooklynella. Clownfishes are very vulnerable to this disease which is mainly caused by stress during transportation.

It would be useful if you quarantine your fishes fisrt.

thanks a lot marineman... if it is what the disease what u discribe .. will it affect the rest of the fish other than clown ... by the way can the uv light destroy the dna of the bacteria?? in the meanwhile i am not doing any thing to the tank ...

thanks!

by the way can the uv light destroy the dna of the bacteria??

UV kills BOTH good bacteria (food for corals) and bad bacteria (food for nuisance algae growth), not sure if it helps to prevent disease outbreak. If your tank does not have nuisance algae and you are keeping corals, you can do without UV light.

the disease seem to be under control after i introduce pro series cure ich by AquaPham... seem to be effective ...

the medication seem to be able to control parasite other than ich ... and it does not contain copper , at least it is what it claimed to be ...
