Flame Fin Tomini Bristletooth Tang - Ctenochaetus tominiensis

Flame Fin Tomini Bristletooth Tang (Ctenochaetus tominiensis)

The Flame Fin Tomini Tang is a compact, algae-grazing powerhouse with striking golden accents and an elegant, angular silhouette. Native to reef slopes across the Western Pacific, this species features a dusky brown body offset by bright yellow to orange fins and distinctive tail streamers. It’s one of the few surgeonfish suitable for smaller reef tanks, offering both utility and beauty.

Tank Requirements

A minimum of 55 gallons is recommended, though larger tanks are preferred for adult specimens. Provide open swimming space paired with live rock for grazing and shelter. Strong, stable water quality and good oxygenation are key to long-term health. These tangs benefit from steady flow and appreciate tanks with high algae availability or regular supplemental feeding.

Color, Personality, and Hardiness

Flame Fin Tomini Tangs are eye-catching yet practical, combining vivid fin coloration with nonstop algae control. They are active, alert, and generally peaceful, though they may become territorial with other tangs—especially similar-shaped bristletooth species. Hardy and disease-resistant, they adapt quickly to captivity and are a reliable addition to community reef systems.

Diet and Feeding

Primarily herbivorous, Tomini Tangs thrive on a diet rich in marine algae and vegetable matter. Feed a mix of dried seaweed (nori), spirulina, and algae-based pellets, along with occasional mysis or brine shrimp. Regular grazing keeps their digestive system healthy—offer multiple small feedings daily if algae is limited in the display.

Tankmates and Behavior

Peaceful and reef-safe, this species integrates well into mixed reef communities. Avoid housing with other tangs unless in larger tanks (100+ gallons), as they may defend grazing territory. They will not harm corals or inverts, making them ideal for reef setups. Their industrious algae-eating habits help maintain a clean, balanced aquarium ecosystem.
