Got a naso tang from a Lfs and put it in qt at home. Looking at it more closely I am seeing white spots on the fins I thought ich was more on the body? The most frustrating thing right now though is I can't seem to get it to eat. Tried emerald entree and nori with garlic and he isn't touching anything... any ideas to help with food or if he has some sort of disease that could be bothering him?
