Pycnochromis
Pycnochromis is a genus of marine ray-finned fishes belonging to the family Pomacentridae, the damselfishes. These fish are found in the western Indian Ocean. They are commonly known as chromis damsels or, more specifically, as pycnochromis damsels. The genus currently contains five described species.
Characteristics
Pycnochromis damsels are small fish, typically reaching a maximum size of around 10 cm (4 in). They are characterized by their deep, compressed bodies and their vibrant coloration. Most species have a distinctive yellow or orange body with dark stripes or spots. Their fins are often brightly colored, with blue or yellow edges. They possess a single dorsal fin, which is often elongated in males, and a forked caudal fin.
Environment
Pycnochromis species are primarily found in coral reefs and rocky shores, often in areas with strong currents. They are typically found in shallow water, but some species may venture into deeper waters. They are typically found in the western Indian Ocean, including the Red Sea, the Gulf of Aden, and the coast of East Africa.
