Hi, I recently got a Royal Clown Knife from my LFS and he is pretty shy. It has been one week since I got him, and he has been hiding behind the log for the whole time. I saw him eat some feeder fish at the store but I have yet to see him eat in my tank. Other fish in my tank also eat the feeders, so I am afraid that the clown won't be able to get any. Is there some way to get him to eat?
