Care

Cortez Damselfish are relatively easy to care for, but they can be territorial, especially as they mature. They require an aquarium with plenty of rockwork and hiding spaces to feel secure. A varied diet of meaty foods, algae, and high-quality marine flake or pellet food will help maintain their vibrant colors and overall health.

Reproduction

In the wild, Cortez Damselfish are known to be substrate spawners, laying their eggs in nests which are fiercely guarded by the male until they hatch. In the aquarium, breeding can be a challenging endeavor, and it is not commonly pursued by hobbyists.

Habitat

Cortez Damselfish are native to the tropical waters of the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands. They prefer shallow, rocky reefs and are often found at depths ranging from the intertidal zone to about 12 meters (40 feet).
