Behaviour and Habitat In the wild, Bicolour Anthias are found in small groups, often led by a dominant male. They exhibit peaceful behaviour toward tank mates but can be shy if housed with overly aggressive fish. Providing plenty of hiding spots and live rock enhances their sense of security and encourages natural behaviour.

Water Quality: Maintain stable and pristine water conditions to support their health and vibrant colouration. Lighting: Moderate to bright lighting replicates their natural reef environment. Flow: Moderate to strong water flow mimics the currents of their native habitat. Diet Bicolour Anthias are carnivorous and require a varied diet of high-quality foods to meet their nutritional needs.Primary Foods: Mysis shrimp, brine shrimp, finely chopped seafood.
