Last Friday, I introduced an ocellaris and a black ocellaris to my 55 gallon FOWLR tank. Over the past week the black ocellaris has been very in active. Every since the the day I put him in my tank he has been breathing fast. Observing him over the past few days I've noticed some white stuff forming under his left side fin. I'm not sure what it could be but could someone please go look at the photos on my profile and inform me on what it might be and how to treat it? Thanks!
