Manini (Convict Tang).

The striped "convict" surgeonfish that schools across Hawaiian reefs — one of the most common fish you'll spot snorkeling.

On exhibit

Manini, the convict tang, is one of the most familiar fish on every Hawaiian reef — a silver-white surgeonfish marked with bold black vertical bars that look like an old prison uniform. They form loose schools that move along the reef like a grazing herd, scraping algae from the rocks.

The Hawaiian word manini also means "small" or "insignificant" — a teasing reference to the fish's modest size. Despite that, schools of hundreds can quickly defoliate algae from a stretch of reef, helping coral compete for space.

Like all surgeonfish, manini have sharp scalpel-like spines at the base of the tail that can flick out when the fish is handled. Juveniles spend their first months in tidepools, sheltered from larger predators, before joining the adult schools out on the reef.
