Nice, fairly hardy fish for a FOWLR system. Needs a large tank (180+) as an adult but slow growing. Have lots of live rock for grazing and offer it a good varied diet of greens and meaty foods. Not much different in terms of upkeep than most other members of the family. I kept one for awhile years ago. It was somewhat pushy with a few fairy wrasses and a butterfly, but nothing major. Don't buy an adult specimen unless you actually see it eat a variety of foods. Try to find one in the 3-5 inch range. They seem to adapt better.
