MINE IS THE SAME WAY!
He constantly tries to pull snails off the glass and he pretty much totally destroyed a zoa frag I just added. I had a 4 stripe damsel and they seemed to get along fine but then the damsel disappeared one day. I had to move the tank like two days after that so I tore the tank apart looking for the fish or its remains but found no sign of it.
Mine is around 2" long
