How long have you had it in your tank? I have one with a dwarf fuzzy lion, triggers and a lunare wrasse he spend most of the time under a piece of tabletop coral skeleton, BUT when he sees me coming he is out at the front of the tank wagging like a little puppy that hasen't eaten in days. It took about a week for him to get comfortable with his surroundings. Mine loves krill and silversides.
