Common name: Giant damselfish

General information

The California Damsel, Microspathodon dorsalis, is a vibrant species of damselfish native to the Eastern Pacific. It is known for its striking blue coloration and assertive demeanor. Juveniles exhibit a brilliant blue hue with electric blue spots, which fade to a darker, more subdued tone as they mature. This species is not as commonly kept as some other damselfishes due to its territorial nature.

Care

California Damsels are hardy fish that can adapt to a variety of aquarium conditions. However, they are known for being territorial and may become aggressive, especially in smaller tanks. A larger aquarium with plenty of rockwork and hiding spaces can help mitigate aggressive behavior. They are omnivorous and will accept a wide range of foods, including frozen, flake, and live offerings.

Reproduction

In the wild, California Damsels are known to be substrate spawners, laying their eggs in a carefully cleaned area, often on a flat rock. The male then guards the eggs until they hatch. Reproduction in the home aquarium is rare, but providing a stable environment with plenty of hiding spaces can encourage breeding behavior.

Habitat

Microspathodon dorsalis is found in rocky reefs and kelp forests from the Gulf of California to Peru, including the Galapagos Islands. They prefer areas with strong water movement and are typically found at depths ranging from the intertidal zone to about 12 meters.
