General information

The Filament-finned Damsel, scientifically known as Neopomacentrus filamentosus, is a small and colorful member of the Pomacentridae family. This species is known for its striking appearance, with a vibrant blue body and elongated filamentous dorsal fin rays that give it its common name. It is a popular choice among aquarists due to its hardiness and the dynamic visual interest it adds to a reef aquarium.

Care

Filament-finned Damsels are relatively easy to care for, which makes them suitable for both beginner and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. These fish are omnivorous and will accept a variety of foods, including frozen and flake foods, but a diet that includes marine algae and small meaty foods will help maintain their coloration and health.

Reproduction

Like many damselfish, the Filament-finned Damsel is an oviparous species, with the female laying eggs that are then fertilized by the male. The male typically guards the nest site, which is often located on a flat surface within the aquarium. The eggs hatch into planktonic larvae, which will require specialized care if the aquarist intends to raise them to adulthood.

Habitat

Neopomacentrus filamentosus is native to the Indo-Pacific region, where it is commonly found in shallow reefs and lagoons. In the wild, these fish prefer areas with abundant coral growth and are often observed in small groups or pairs. They are well-adapted to a range of environmental conditions within their natural habitat, which contributes to their resilience in the home aquarium.
