Agreed, totaly safe for all inverts. Just make sure to give it nori. My sailfin tang and foxface have an occasional skirmish. One will chase the other from one side of the tank to the other, then get chased back. Lasts a couple of minutes and then they go about their algae hunt again. They feed together from the nori clip and if a piece rips off they grab it from each other till it's gone. Quite fun to watch.
AustinsDad, I think that's a lovely shade of splotchy tan and browns at lights out
