I recently purchased a pair of bicolor anthias at my LFS. I have a couple of questions. First, I have not been able to find bicolor anthias listed in any of the on-line sites. Is there a different name for these guys. They are orange on top and pick on the bottom. I was told that they stay small, 3-4". I would appreciate any help with the ID. Also, I was told that they do better in pairs or groups. Is this true or was I just suckered into buying 2.
