Care

Sunshine Chromis are relatively easy to care for, which makes them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with stable water conditions and plenty of swimming space. These fish are omnivorous and will accept a variety of foods, including small pellets, flake foods, and frozen or live brine shrimp and mysis shrimp. It's important to feed them a varied diet to maintain their health and coloration.

Reproduction

In the wild, Sunshine Chromis form breeding pairs or small groups. They are known to spawn on substrates, where they lay adhesive eggs that are guarded by the male until they hatch. In the aquarium, breeding can be a challenging endeavor, but with the right conditions and a well-matched pair, it is possible to observe their reproductive behavior.

Habitat

Sunshine Chromis are found in the Western Atlantic, from Florida and the Bahamas to the northern coast of South America. They typically inhabit shallow reefs and are often seen in groups hovering above stony corals or other reef structures. In the aquarium, replicating their natural environment with live rock and ample hiding places can help promote natural behaviors and reduce stress.
