The Blue/Green Chromis, scientifically known as Chromis viridis or Chromis cyanea, is a popular and relatively easy-care marine fish. With their vibrant colors and peaceful nature, they are a great addition to both beginner and experienced aquarists' tanks.

Being an omnivore, the Blue/Green Chromis primarily feeds on zooplankton in the wild. In captivity, they can be fed a varied diet consisting of high-quality flake or pellet food suitable for marine omnivores, supplemented with occasional live or frozen foods like brine shrimp or mysis shrimp. They may also graze on algae, so providing some algae-based food or natural algae growth in the tank can be beneficial.

In terms of compatibility, the Blue/Green Chromis is a peaceful fish that can be housed in community tanks with other peaceful species. They typically do well with other small, non-aggressive fish and are known to form small schools, adding to the beauty of your aquarium. However, it's important to note that they may exhibit territorial behavior towards their own species, so providing ample swimming space and hiding spots is recommended.

Reef keepers will be happy to know that the Blue/Green Chromis is reef safe. They do not pose a threat to corals or other invertebrates, making them a suitable choice for reef tanks. Their vibrant colors can add a beautiful touch to any coral reef setup.

This species typically grows to a maximum length of around 3 inches, so a tank size of 20+ gallons is generally sufficient. It is recommended to provide ample swimming space and places to hide or rest, such as live rock or artificial structures.

In summary, the Blue/Green Chromis is an easy-care and peaceful addition to a marine aquarium. Their omnivorous diet, compatibility with other peaceful fish, reef-safe nature, potential adult size of up to 3 inches, and suggested tank size of 20+ gallons make them suitable for both beginner and experienced aquarists. With their vibrant colors and peaceful demeanor, the Blue/Green Chromis can add life and beauty to your underwater oasis.
