Plectroglyphidodon luteobrunneus, also known as the brown damselfish, is a species of damselfish found in the western Pacific Ocean. It is a popular fish in the aquarium trade due to its striking coloration and relatively easy care requirements.
Description & Characteristics
Plectroglyphodon luteobrunneus is a small, brightly colored fish that reaches a maximum size of about 10 cm (4 inches). Its body is typically a deep brown or black color, with a bright yellow or orange band running along the middle of the body. This band is typically more prominent in males than females. The fish also has a distinctive white or yellow margin along the dorsal fin, which is often iridescent in the sunlight. Like many other damselfish, the species has a dark spot at the base of the caudal fin.
Habitat and Occurrence
Plectroglyphidodon luteobrunneus is a reef-associated species that is typically found in shallow, clear water with abundant coral cover. It is a common resident of the Indo-Pacific region, ranging from the Philippines to the Solomon Islands. The species inhabits the tropical marine zone, preferring depths between 1 and 20 meters (3 and 66 feet). They are often found in association with specific coral species, particularly those that provide crevices and overhangs for shelter.
Taxonomy
Plectroglyphidodon luteobrunneus is classified within the family Pomacentridae, which comprises the damselfishes. The species belongs to the Class Teleostei, the most diverse group of ray-finned fishes, and the Order Ovalentaria incertae sedis, which is a clade within the Perciformes.
Feeding
Plectroglyphidodon luteobrunneus is primarily a herbivore, feeding on algae and zooplankton. They play an important role in maintaining the health of their reef ecosystems by controlling algae growth. In captivity, the species can be fed a diet of commercially prepared fish flakes, algae wafers, and frozen brine shrimp.
