Hey I have 2 clownfish about same size if not slightly bigger added same time about 1 week ago. Today I noticed one of the clownfish doesn't eat so I pull him up and saw that something white on his fin. I wonder is this aggression? Also both are in qt tank with copper and treat with prazi, kana,metro for about a week now so I don't think it parasite. The other clownfish is eating normal but this one isn't today. They are both snowstorm. There also few other fish in the tank like copper and and dogface puffer and afoxface
