I have a 90g display, 120 total system volume reef tank with a lot of open swimming area. I picked up a Tomini tang for an awesome price about a month or so ago, it was $40. I acclimated him slowly and put him in. He hid for a while, i thought nothing of it since most fish when introduced to a new home tend to get scared and want to hide. I noticed after a few days though that he only comes out of the hiding spot he made for himself (a cave in my rock work that opens to the back of my tank) when he seems to be hungry and no one is near the tank. I can be across the room and I seem him swim out and eat off the rocks or nori sheets if they happen to be in the tank. If I approach the tank ever he goes right back to hiding.
Any thoughts on this? Would going in and rearranging the rock work help? He is rather plump so I don't think he is starving, and he is the largest fish in the tank and I never see anyone else chasing him around or even bothering him.
