Hello, I bought this baby ocellaris clownfish and he is in my quarantine tank right now. I have noticed that he has this faint white spot on the top of his body, close to his dorsal fin (his dorsal fin might be a bit white too but it's hard to see, he is so small!). He is moving around and eating, acting normal... I went to the aquarium store and they told me that maybe he just has a torn scale or something. They gave me Melafix. He has been on that for 5 days. He still has the white spot... Any idea? Thanks!
