The Cape Damsel, One-spot Damsel, Onespot Damsel, One-spot Demoiselle, or Onespot Demoiselle, scientifically known as Chrysiptera unimaculata, is a small, brightly colored fish belonging to the damselfish family (Pomacentridae). This species is renowned for its distinct black spot on its dorsal fin, which serves as a key identifying characteristic.
Description & Characteristics
The Chrysiptera unimaculata is a relatively small fish, reaching a maximum size of 10.0 cm. Its body is typically a bright yellow or orange color, with a striking black spot on the dorsal fin, which is positioned closer to the tail. The overall appearance of this species is quite vibrant and eye-catching, making it a popular choice for saltwater aquariums.
Habitat and Occurrence
The Chrysiptera unimaculata is a common resident of coral reefs and rocky shores, particularly in the Indo-Pacific region. It is found in shallow waters, with a depth range of 0.0 – 3.0 meters, predominantly in the tropical marine zone. This species is a highly adaptable fish, able to thrive in a variety of environments, but prefers locations with ample algae growth and coral cover.
Taxonomy
The species Chrysiptera unimaculata belongs to the Class: Teleostei, Order: Ovalentaria incertae sedis, and Family: Pomacentridae. This classification places it within the larger group of bony fishes, specifically within the order of “uncertain position” within the Ovalentaria group. The family Pomacentridae encompasses a diverse array of fish, including damsels, clownfish, and chromis, all characterized by their vibrant colors and often, their symbiotic relationship with anemones.
Feeding
The Chrysiptera unimaculata is primarily an herbivore, with a diet consisting mainly of algae. However, it also exhibits omnivorous tendencies, occasionally consuming small invertebrates and zooplankton. In a captive environment, this species can be fed a variety of commercially available foods, including flakes, frozen food (small sorts), brine shrimp nauplii, brine shrimps, copepods, daphnia salina, krill, mysis, and living food. This diverse feeding pattern contributes to the Chrysiptera unimaculata‘s resilience and adaptability in both its natural and captive habitats.
