Care Guidelines
Aquarium Setup:
Bicolour Chromis prefer a well-established reef aquarium with plenty of live rock and hiding spots for comfort. They thrive in a tank with gentle to moderate water flow and a varied substrate. They do best in groups, as they exhibit schooling behavior and feel more secure in the presence of others. Provide ample swimming space as they are active swimmers.
Water Parameters:
Maintain a pH range of 8.1 to 8.4, with stable water temperatures between 24°C and 28°C. A specific gravity of 1.020 – 1.025 should be maintained. Regular water changes, efficient filtration, and protein skimming are essential to maintain pristine water conditions.
Diet:
As omnivores, Bicolour Chromis feed on a variety of foods. Offer a balanced diet of high-quality flake food, marine pellets, and frozen foods like brine shrimp, mysis shrimp, and marine algae. They will also accept live foods, such as copepods and rotifers, which are beneficial for their health and coloration.
Behavior and Maintenance:
Bicolour Chromis are peaceful and do well in community tanks. They are best kept in schools of at least five or more individuals, as they are social and feel more secure in groups. Regular maintenance, including water testing and cleaning, will ensure they thrive in the aquarium.
Compatibility:
These Chromis are reef-safe and peaceful, making them a great addition to community marine tanks with other peaceful species such as clownfish, wrasses, and gobies. They can also coexist with corals and invertebrates. Avoid housing them with aggressive fish or species that may outcompete them for food.
