Ctenochaetus binotatus, commonly referred to as the Chevron Tang, is a small species of tang prized for its unique chevron-like markings and effective algae grazing habits. This fish is a valuable addition to marine aquariums, particularly for hobbyists seeking a peaceful, reef-compatible surgeonfish that contributes to natural algae control.
Care Level: Moderate. This species requires stable water parameters and a well-established tank with plenty of live rock for grazing.
Temperament: Generally peaceful but may show mild territorial behaviour towards conspecifics or similar tang species. Best kept singly or in a large tank with ample space.
Diet: Primarily herbivorous. Feed a varied diet rich in marine algae, spirulina, and high-quality herbivore flakes or pellets. Supplement with occasional meaty foods to ensure balanced nutrition.
Minimum Tank Size: 120 litres (approximately 30 gallons) to provide sufficient swimming space and grazing surfaces.
Reef Compatibility: Yes, with caution. While generally reef safe, monitor interactions with small invertebrates and corals, as tangs may occasionally nip.
Lighting and Water Flow: Standard reef lighting and moderate water flow are suitable to mimic natural reef conditions.
Placement: Provide plenty of live rock for grazing and hiding spots. Introduce this tang after the tank is well established to reduce stress and aggression.
Origin: Indo-Pacific region.
Maximum Size: Up to 15 cm (6 inches) in length.
