I got my first shipment of tangs for my new 180 a few days back, and of them the Blue Eye Kole Tang hasn't strayed from his cave other than maybe to grab a couple floating pieces of food. If I look from the right angle I can see him swimming a bit so I know he's alive. But he's staying in his cave, whether it's bullying from the other tangs (got a mean purple), stress from all the shipping, or he's just happy and fed enough in there that he doesn't want to go out. Maybe he'll venture out eventually.
What fish in your tank do you never see out and about?
