I've been treating two clowns for ick with copper for two weeks in qt and the smaller one appears to have a little fin rot (or is being bullied by the big one which I've witnessed during feeding).
If it is fin rot I assume it is from ammonia being present (cannot get it below .25 no matter how many PWC
I do) along w aggression from big sis. So since I've already invested this much $ and time I'm thinking of treating w erythromycin. Is it ok to treat with copper and erythromycin?
Temp is 78
