Mata Tang

Overview

The Mata Tang (also called the Elongate Surgeonfish) is a large, sleek, blue-grey tang with fine dark striping and a yellow patch near the tail, growing considerably larger than many of the more commonly kept tangs. Unlike most Acanthurus species which are strict algae grazers, it feeds more on zooplankton in open water, making its dietary needs slightly different.

It's an active, fast-swimming fish that needs a large tank with plenty of open water alongside rockwork, and doesn't do well long-term in tanks sized for smaller surgeonfish. Given the right space it is a hardy, rewarding fish to keep.

Because of its size and swimming requirements it's best suited to a large, established reef or fish-only system rather than a first tang purchase.

Compatibility

Mata Tangs can show aggression toward other tangs, particularly similarly shaped Acanthurus species, so care with stocking order matters in tanks with multiple surgeonfish. They are generally peaceful with unrelated community fish.

This species is fully reef safe with corals and invertebrates, posing no risk to sessile reef life.

Health & quarantine

A minimum four-week quarantine is recommended given the general ich susceptibility of Acanthurus tangs, along with close observation of appetite and breathing in the first two weeks. Strong water flow and stable, high-quality water support this species' health, particularly given its more open-water, plankton-feeding lifestyle compared to typical algae-grazing tangs.
