Tomini Tang

Overview

The Tomini Tang is a slender, attractive bristletooth tang with a warm brown body, fine blue pencilling, and a bright yellow tail, making it one of the more visually appealing members of the Ctenochaetus genus. It shares the same detritus and diatom-sifting feeding style as its relatives, making it a genuinely useful clean-up fish as well as an attractive display animal.

It's considered one of the hardier and more forgiving tangs for home aquariums, tolerating a range of tank sizes better than many larger Acanthurus species, and is a common recommendation for a first tang purchase.

Given adequate space and a stable, established tank it's a low-maintenance, long-lived addition to a reef system.

Compatibility

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

This species is fully reef safe and won't bother corals, clams, or invertebrates.

Health & quarantine

As a Ctenochaetus species, the Tomini Tang is one of the hardier tangs, though it's still susceptible to marine ich like all surgeonfish, so a minimum four-week quarantine is recommended. Good water flow and a varied algae-rich diet support long-term health and colour.
