Last week I brought home an Atlantic Blue tang from my lfs
. Meanwhile he is doing fine, eating and all that I noticed that he has a grey scar near his pectoral fin. I feed 1 sheet of nori algae a day. I tear the algae in haft so he kinda gets fed 2 times a day with flakes or frozen shrimp. My tank Is currently in a 100 gallon Fowlr
. I've seen no aggression out of his tankmates, water quality is fine too. I personally don't think it's a disease or anything like that, more like he scratched himself on a piece of live rock but I came here to check!
In the picture the large grey patch on him is what we're focusing on.
