Gorgeous fish indeed. Their downside is that they're voracious invertebrate predators. They go after any snails, crabs, hermits, sea cucumbers, bristleworms, anything. And their method of hunting is somewhat destructive for a reef environment. They literally pick up small rocks/pebbles and drop/throw them around the tank, searching for inverts underneath them. So you really have to keep a tank without a good cleanup crew, and without any unsecured small rocks. Kind of troublesome in a reef environment. GREAT fish only species though...
