General information

The Mimic Damselfish, scientifically known as Pomacentrus imitator, is a captivating species for marine aquarists due to its vibrant coloration and dynamic behavior. This species is often mistaken for the more aggressive Pomacentrus moluccensis, but it is actually more peaceful and can be distinguished by subtle differences in coloration and fin structure.

Care

Mimic Damselfish are relatively hardy and can adapt to a variety of tank conditions, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and territorial establishment. A varied diet of meaty foods, algae, and high-quality commercial feeds will help maintain their health and color vibrancy.

Reproduction

In the wild, Pomacentrus imitator forms breeding pairs that engage in elaborate courtship displays. They lay their eggs on a flat surface, which the male then guards and tends to until they hatch. While breeding them in captivity can be challenging, it is possible with careful attention to water quality and feeding.

Habitat

Native to the Western Pacific, particularly around Indonesia and the Philippines, Mimic Damselfish are found in shallow, coral-rich areas of the reef. They prefer environments with strong water movement and access to stony corals or branching corals for refuge.
