Description
A massive, deep-bodied surgeonfish with a light gray to olive-blue body, a prominent bony horn projecting from the forehead of adults, and two fixed, blue-outlined keel-like blades on each side of the tail base. It is a peaceful open-water grazer that ignores corals and invertebrates but can be territorial toward other Naso and similarly shaped tangs, so keep just one per system. Requires an extremely large tank with wide-open swimming lanes, brisk flow, and heavy vegetable feeding, dried nori several times daily plus algae-based prepared foods; handle with a container rather than a net, as the caudal blades cut skin and shred mesh.
Reef Safe
