I just introduced a Banggai last night while it was dark and it had atleast 8 hours before the lights came back on to get a feel for the tank. So far it doesn't seem like it has checked out the rock for any hiding places (which I understand they like to hid during the day), it just hangs out at the top of the water in the open area or down near the sand by the corner of the tank. I have a 65 gal with only 65lbs of LR so it has plenty of room to swim around in. Do your Banggai do the same thing, or is this odd? Also, could the current be too powerful for it? I have two 1200 Maxijet powerheads, one on each side of the tank. There are no other fish in the tank, only Anthelia, mushrooms, snails, micro hermits and a normal hermit crab.
