Chocolate-Dip Chromis

Pycnochromis hanui

The Chocolate-dip Chromis, a damselfish species endemic to Hawaii, is recognized by its unique coloration. This small fish, reaching a maximum length of 6.0 cm, features a body that appears as if the front half has been dipped in chocolate. Its body is brown with a distinctive black spot at the base of the pectoral fin, while the caudal fin, caudal peduncle, and adjacent parts of the dorsal and anal fins are white. This species is often seen in mass groups above coral reefs, residing in both inshore and offshore environments. Chocolate-dip Chromis inhabit tropical waters of the Eastern Central Pacific, specifically around the Hawaiian Islands. They are typically found at depths ranging from 6 to 50 meters, although most occurrences are shallower than 40 meters. As planktivores, they feed on plankton, contributing to their role in the reef ecosystem. During breeding, males are known to guard and aerate the eggs, which adhere to the substrate, ensuring their health and development. Divers encountering the Chocolate-dip Chromis will likely observe them in aggregations, adding a dynamic aspect to the coral reef scenery. These fish are harmless to humans and are classified as Least Concern by the IUCN.
