I assume you mean Maculosus Angel? How large is your tank and how long has it been up and running? Is this a tank raised or a wild caught fish? Not sure if you realize it or not, but that is not really a reef safe angel.. I certainly wouldn't keep one in my tank. Not only do they get huge but they require a pretty large tank.. What are you feeding it? I'd suggest frozen mysis, nori seaweed and if you can get your hands on LRS Fish Frenzy, that would be your best bet.
