I have one, I have to respectfully disagree about competing for food. Mine is extremely fast, and out competes all my other fish, including 6 anthia's, blue sided wrasse, clowns, pacific blue tang. This fish takes flake out of my fingers, and clears up a 3"x 6" strip of nori in less than 5 minutes. He bites the tips of my green brittle stars legs right off, and nips my clam. He is extremely aggressive. If you like peaceful community fish, pass this guy up. I would say, if you have good water quality, and high flow, like Tunze pumps, go for it. Find a good LFS with quality fish, and quarantine, because it will have ich. And IMO, this fish needs to eat a lot. They are very active, and burn food fast. HTH
