Foods & Feeding: The Squaretail Tang is primarily herbivorous, feeding on algae and plant matter. It is an excellent algae eater and will help control unwanted algae growth in your aquarium. In captivity, it should be offered a variety of algae-based foods such as nori, spirulina, and algae wafers. You can supplement its diet with occasional fresh vegetables like zucchini or spinach. Meaty foods can be provided as occasional treats to ensure its health.

Reef Compatibility: The Ctenochaetus truncatus is considered reef-safe and is a beneficial addition to reef tanks. Its algae-eating habits help keep your tank clean, reducing algae buildup without harming corals or invertebrates.

Captive Care: This species is hardy and relatively easy to care for. A tank with plenty of live rock and space for grazing is essential for the Squaretail Tang to thrive. This tang is peaceful but may become territorial towards other tangs or similarly-shaped fish, so it’s best to house it with compatible species in a tank with plenty of space to reduce aggression.

The Ctenochaetus truncatus is a vibrant and functional addition to your reef or community aquarium, offering both beauty and utility with its algae-eating habits and striking yellow eyes. Its mostly peaceful nature and ease of care make it an excellent choice for aquarists looking to maintain a healthy and algae-free tank.
