Size: 10 cm Family: Pomacentridae Minimum Tank Size: 100 litres Overview: The Blue Green Reef Chromis, scientifically known as Chromis viridis, is a popular and attractive choice for marine reef aquariums due to its easy care, striking appearance, and peaceful nature. This damselfish features a beautiful gradient coloration, with a light blue dorsal side that transitions into a pale green belly. Its calm demeanor makes it suitable for a variety of community setups, including with other fish, invertebrates, and corals. Originating from the Indo-Pacific and South Pacific reefs, Blue Green Reef Chromis are typically found schooling in large groups among branching corals like Acropora. In the home aquarium, they thrive in similar environments and will actively swim at all levels of the tank. A small school of at least six individuals can add a shimmering, dynamic element to any well-established reef system. Hardy and long-lived, the Blue Green Reef Chromis can survive between 8 to 15 years in a tank with excellent water quality. To ensure optimal health, provide a varied diet including meaty foods, herbivore flakes, and frozen preparations, feeding multiple times a day. Vitamin-enriched foods can help maintain their vibrant coloration. Breeding in captivity is possible, though it typically requires a large, well-maintained aquarium with perfect water parameters. Interestingly, mature males preparing to nest will display a muted yellow coloration.
