Have had him for a little over a month and he is finally getting along with the other tangs in the tank and now I see these dots … they were not there last night or two nights ago I’m sure… no other tangs or fish have dots…I do have a lot of torches, hammers and bubble tips so maybe be got stung or into a fight with the other tangs again? I really don’t think it’s ich after seeing pictures and others post.
