Temperament

Peaceful

Description

A large western Pacific parrotfish that changes dramatically with age and sex: juveniles and females are pale grey-brown with faint white barring, while terminal males turn blue-green with pink and lime accents and a green facial 'moustache' marking. It is generally peaceful toward tankmates but is a relentless grazer that scrapes rock with fused beak-like teeth, so it will nip stony corals, clams and coralline algae and produce clouds of sand and detritus. Only suitable for very large systems (150 gallons minimum, more for adults) with abundant live rock, open swimming space and heavy supplemental feeding of algae-based foods, as many specimens starve in captivity.

Reef Safe

No

Environment

Requires a well-established aquarium with plenty of live rock for grazing and hiding. Water should be well-oxygenated with stable parameters.

Behavior

Generally peaceful but can be territorial, especially in smaller tanks. It is an active swimmer and requires plenty of space to roam.
