Two Spot Bristletooth Tang (Ctenochaetus binotatus)

Ctenochaetus binotatus is an industrious detritus and diatom grazer named for two dark spots at the base of its dorsal and anal fins. It uses its bristle-like teeth to stir up and consume fine algae films and detritus from rock surfaces, making it a natural cleaning crew member. Hardy and generally peaceful, it suits community reef systems where flow and open swimming space are provided.

Provide a 300 L minimum tank with strong circulation and ample live rock. Feed nori, spirulina, and algae-based flake daily. Acclimate to stable salinity 1.020–1.025 SG and temperature 23–27°C. Generally compatible with other tangs in large systems; quarantine before introduction.
