He sleeps and spends a good part of his day hiding in a cave that pretty much spans the width of the tank and you cant get a net into. I would take a turkey baster and try to flush him out of the cave, but this fish is so jumpy that I would bet that he just flattens himself against a wall, loses his color and breaths heavily instead of moving. Not only this, but the fish is probobly on 3-3.5", so he ca still get into relitively small holes pretty easily.
i took the net out and put more seaweed in it b/c my powder blue tang is the only one going in the trap to get the food.
