So I have a Regal tang in my 80g who will not eat algae. He swims around happily, and will eat his seaweed, but will not touch the GHA I had, or any I get on the glass or rocks. Do you think that he is just not hungry due to I feed him everyday and he get seaweed? I am just wondering since most tangs are supposed to eat algae, from what I have heard anyways. Any thoughts would be appreciated. Thanks!
