Sailfin tang

Care at a glance

Overview

A hardy algae grazer that is reef safe but grows large and swims hard, so it needs a big tank; it is somewhat less aggressive than the purple tang but will still defend a territory against other tangs and similarly shaped fish. Keep one per tank and add algae on a clip daily. Its only reef risk is occasional nipping of coral polyps while grazing, which is uncommon in a well-fed fish.

In the wild

A large western Pacific surgeonfish of shallow, algae-rich reefs and lagoons, where it grazes filamentous and larger algae over rock and rubble. It is a vigorous, near-constant swimmer that erects its tall dorsal and anal fins to look much bigger when threatened. It needs a long tank with wide open swimming lanes and plenty of grazing surface.

Good to know

Zebrasoma veliferum is named for its enormous sail-like dorsal and anal fins, veliferum meaning sail-bearing, which when raised make the fish's profile nearly circular and far larger than its body. It reaches about 30 cm in the aquarium, one of the largest Zebrasoma species, and juveniles are boldly barred in yellow and dark brown before the adult pattern develops.
