Ctenochaetus binotatus, commonly known as the Medium Tang, is a popular choice for marine aquarium enthusiasts seeking an effective algae grazer with striking appearance. This species is easily recognised by its distinctive bristle-like teeth, which it uses to scrape detritus and algae from rock surfaces, helping to maintain a clean and healthy aquarium environment.
Care Level: Moderate care is recommended, as this tang requires stable water conditions and a well-established tank with ample live rock for grazing.
Temperament: Generally peaceful but may show territorial behaviour towards conspecifics or similar tang species. It is best kept singly or in a large tank with plenty of hiding spaces.
Diet: Primarily herbivorous, feeding on algae and detritus. Supplement diet with high-quality marine algae sheets, spirulina, and specialised herbivore pellets to ensure balanced nutrition.
Minimum Tank Size: A minimum of 120 litres (approximately 30 gallons) is recommended to provide sufficient swimming space and grazing area.
Reef Safety: With caution. While generally reef safe, this tang may occasionally nip at soft corals or clam mantles, so monitor behaviour closely in reef setups.
Lighting and Water Flow: Standard reef aquarium lighting is suitable. Moderate water flow is preferred to mimic natural reef conditions and support healthy algae growth.
Placement: Provide plenty of live rock for grazing and hiding spots. Avoid overcrowding to reduce stress and territorial disputes.
Origin: Not Provided.
Maximum Size: Approximately 15 cm (6 inches) in length.
