I noticed two black spots on my coral beauty. The are both right above his eyes. Almost looks like eyebrows. He is a recent addition to my tank ( about 1 week ) but came from another reefers tank and has only had these spots for a day or two. He is acting and eating fine but in addition to the discoloration the spots look like a wound, like it penetrated his scales. The fish is the biggest in the tank and I have never seen any of the others pick on him. Any thoughts as to what this could be?
