Ctenochaetus tominiensis | L

The Tomini Tang (Ctenochaetus tominiensis) is a visually captivating surgeonfish native to the Indo-Pacific region. Recognised for its vibrant colour patterns and specialised bristle-like teeth, this species excels at grazing on microalgae and detritus, making it a valuable addition to established marine aquariums.

Care Level: Moderate. This species requires stable water parameters and a well-maintained environment.

Temperament: Generally peaceful but may show territorial behaviour towards conspecifics or similar tang species.

Diet: Primarily herbivorous. Provide a varied diet rich in marine algae, spirulina, and high-quality herbivore flakes or pellets. Supplement with occasional meaty foods.

Minimum Tank Size: Recommended 120 litres (approximately 30 gallons) or larger to allow adequate swimming space and territory.

Reef Compatibility: Yes, safe for reef tanks. The Tomini Tang does not typically nip at corals or sessile invertebrates.

Lighting and Water Flow: Standard reef lighting and moderate water flow are suitable, replicating natural reef conditions.

Placement: Mid to upper levels of the aquarium, where it can graze on algae-covered surfaces.

Origin: Indo-Pacific region.

Maximum Size: Up to 20 cm (approximately 8 inches) in length.

When introducing the Tomini Tang, ensure a well-established aquarium with stable water quality and ample hiding places. Avoid housing multiple tangs of the same species unless the tank is very large to reduce aggression. Regular feeding of algae-based foods will promote vibrant colouration and health.
