Common name: Longfin Cardinalfish

General information

The Longfin Cardinalfish, scientifically known as Taeniamia macroptera, is a striking species appreciated for its elongated fins and peaceful demeanor. This nocturnal fish is a member of the family Apogonidae and is often found in small groups hovering in sheltered lagoons and reef slopes.

Care

In the aquarium, Longfin Cardinalfish require a well-established setup with plenty of hiding spots. They thrive in a peaceful community and can be shy, so providing a dimly lit environment with subdued lighting can help them feel more secure. They are omnivores and will accept a variety of foods, including small meaty items and quality flake or pellet foods.

Reproduction

Like many cardinalfish, Taeniamia macroptera exhibits mouthbrooding behavior. The male carries the fertilized eggs in his mouth until they hatch, providing protection from predators. This fascinating reproductive strategy can sometimes be observed in the home aquarium.

Habitat

The Longfin Cardinalfish is native to the Indo-West Pacific region, where it prefers reef-associated environments. It is typically found at depths ranging from shallow waters to about 30 meters deep. Hobbyists should aim to replicate these conditions to ensure the well-being of these fish in captivity.
