I have found them to be peaceful, beautiful and outgoing. On the downside, they can scare the h--l out of you when they wedge themselves into a crevasse in the rockwork, something they do when they are frightened, or sleeping. They require lots of swimming space, and must be quarantined since, like most tangs, are susceptible to ich. They like greens, but adults should receive meat too. The bottom line is that you will enjoy having one in your tank.
