The Ctenochaetus cf. striatus is a medium-sized tang belonging to the family Acanthuridae, commonly appreciated for its specialised algae-grazing habits. This species is often sought after by marine aquarists aiming to maintain natural algae control within their reef or fish-only systems.
Due to the cf. designation, exact origin and maximum size can vary, so conservative care practices are recommended. This tang is generally peaceful but may show territorial behaviour towards conspecifics or similar tang species, especially in smaller tanks.
Care Recommendations:
- Tank Size: A minimum of 120 litres is advised to provide ample swimming space and reduce territorial stress.
- Diet: Primarily herbivorous, this species thrives on a diet rich in marine algae and seaweed. Supplement with high-quality herbivore flakes, pellets, and occasional meaty foods to ensure balanced nutrition.
- Compatibility: Compatible with a variety of peaceful tank mates but avoid housing with aggressive or highly territorial fish. Caution is advised when keeping multiple tangs.
- Water Parameters: Maintain stable marine conditions with temperature between 24-27°C, salinity around 1.023-1.025 SG, and excellent water quality.
Regular monitoring and a well-established aquarium environment will help ensure the health and longevity of this tang. Its algae-grazing behaviour makes it a valuable addition to many marine setups.
