I recently purchased a 6" hippo tang. Immediately upon entering the tank, he dove for the rockwork. The other inhabitants are listed in my profile. None of the others even seemed to notice, and there is plenty of space in the tank. I've seen him dart out for food, which is a good sign, but he seems absolutely terrified of me. In 3 days, I saw him for a split second. How long can I expect this to last? Any tricks for making him less shy? I know he is interested in food but there is no way he is getting enough right now. Any suggestions?
