Care

Blacksmith Chromis are relatively easy to care for and can adapt to a range of water conditions, which makes them suitable for both beginner and experienced aquarists. They thrive in well-oxygenated water with strong water movement and plenty of rockwork or coral for shelter. A varied diet of meaty foods, algae, and high-quality prepared foods will help maintain their health and coloration.

Reproduction

In the wild, Blacksmith Chromis form breeding pairs during the spawning season. They lay their eggs on the substrate or on the underside of ledges, where the male will guard and tend to the eggs until they hatch. In the aquarium, breeding can be a challenging endeavor and is typically only attempted by experienced hobbyists.

Habitat

Blacksmith Chromis are found in the coastal waters of the eastern Pacific, from California to southern Baja California. They inhabit rocky reefs and kelp forests, often in large schools, and can be found at depths ranging from the intertidal zone to about 30 meters.
