ClownFish ???? Help Please !

[cj96ss]

I have 2 Orange Clownfish and one Black one .. Anyways I have had the Orange ones (nemo looking) ones for over a month great active fish .. I have had the black for about a week. Anyways Today It looks like these fish are Shedding ... I mean like the skin above there fins looks like its falling off and all that ... Any reason why?

I'm no expert at all but do they seem agressive towards each other. I heard the black ones are agressive in general but I always thought different clowns cant be kept in the same tank. Maybe they are fighting and the one that looks like it is sheeding is really getting bitten.
