The Chromis chromis, commonly known as the Damselfish, is a small, vibrantly colored fish belonging to the Pomacentridae family. This species is widely recognized for its distinctive appearance and its intriguing social behavior.
Description & Characteristics
The Damselfish is a relatively small fish, reaching a maximum size of 25.0 cm. Its body is typically oval-shaped with a slightly compressed profile. Its coloration is one of its most prominent features, with a vibrant blue body that fades to a lighter shade on the ventral side. The Damselfish’s fins are also a striking blue, while its anal fin displays a prominent black margin.

It is most frequently found in the Eastern Atlantic, with its distribution extending from the Azores and the Canary Islands to the Cape Verde Islands and Senegal. Its presence in these regions is often associated with coral reefs, rocky outcrops, and seagrass beds. The Damselfish typically inhabits shallow waters, with a depth range of 2.0 – 40.0 meters, favoring locations within the Neritic zone.
Taxonomy
The species Chromis chromis belongs to the family Pomacentridae, which comprises a diverse group of fishes commonly known as damselfishes. It is classified under the Order Ovalentaria incertae sedis and the Class Teleostei, the latter representing a large and diverse group of bony fishes.
Feeding
The Damselfish is an omnivorous species, exhibiting a diverse diet that includes both plant and animal matter. Its feeding habits are primarily focused on the consumption of small invertebrates, such as zooplankton and brine shrimps. However, their diet can also include algae, flakes, frozen foods, krill, living food, and mysis. Their foraging behavior is often characterized by a methodical approach, meticulously scanning the substrate for potential food sources. Their feeding habits play a crucial role in the maintenance of ecological balance within their marine habitats.
