The Yellow-spotted Chromis, Yellow-tail Puller, scientifically known as Chromis kennensis, is a vibrant and active fish species that is often spotted darting through coral reefs. This species is readily recognized by its bright yellow tail and the distinctive yellow spots scattered across its body.
Description & Characteristics
Chromis kennensis is a relatively small fish, typically reaching a maximum length of around 10 cm. Its body is elongated and oval-shaped, with a somewhat compressed profile. The body is primarily a pale, bluish-grey color, with prominent bright yellow spots scattered over the dorsal and lateral surfaces. The most striking feature of this species is its brilliant yellow tail fin, which is often used to attract mates and display dominance.
Habitat and Occurrence
Chromis kennensis is a reef-associated species, found primarily in shallow waters and within the intricate structures of coral reefs. These fish are particularly common in the Indo-Pacific region, ranging from the Red Sea and the east coast of Africa to the Pacific Islands. Their preference for coral reefs leads them to inhabit various marine zones, including the epipelagic and reef zones.
Taxonomy
Chromis kennensis is classified within the family Pomacentridae, which encompasses a diverse group of fish commonly known as damselfishes. This family belongs to the Order Ovalentaria incertae sedis, a large group of fish with a diverse range of adaptations. The classification of the Order Ovalentaria is currently under review, and its precise relationship to other fish groups remains the subject of ongoing research. The family Pomacentridae is further categorized within the Class Teleostei, which represents the vast majority of bony fishes.
Feeding
Chromis kennensis is primarily a zooplankton feeder, actively foraging on a variety of small invertebrates. These include amphipods, copepods, crustaceans, and krill. Other common food sources include daphnia salina and mysis. Their diet is crucial for their survival and ensures their role within the delicate balance of reef ecosystems.
