hey i just got a new sunburst anthias. from the start it was in the bottom coner of the bag. acclimated over the next 4 hours, slowly. put him in and he went straight to the bottom. i see him swim a little but never more than a 1/4" off the bottom then rests between some rocks. been sitting there kinda sideways. i know they hide sometimes for weeks but do they normally "wedge" themselves in rocks.
