Care

In the aquarium, Pacific Creolefish require a spacious tank with plenty of open water for swimming, as well as rockwork or caves for hiding. They are carnivorous and should be fed a varied diet of meaty foods such as shrimp, squid, and fish flesh. It's important to note that they can grow quite large, so they are best suited for larger aquarium systems.

Reproduction

In the wild, Pacific Creolefish are known to form spawning aggregations, which can be a challenge to replicate in the home aquarium. They are not commonly bred in captivity, and most specimens in the hobby are wild-caught.

Habitat

Pacific Creolefish are typically found in the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands. They inhabit rocky reefs and steep slopes, often in strong current areas, at depths ranging from shallow waters to over 100 feet.
