Common name: Redspot cardinalfish

General information

The Ruby Red Dragonet, Ostorhinchus rubrimacula, is a small and vibrantly colored fish that adds a splash of color to any reef aquarium. It is known for its striking red spots and elegant finnage. This species is relatively new to the aquarium trade and is appreciated for its peaceful demeanor and unique appearance.

Care

Ruby Red Dragonets are suitable for well-established aquariums with plenty of live rock and a mature sand bed, which provide natural feeding grounds for these fish. They primarily feed on small crustaceans such as copepods and amphipods. It's crucial to ensure a sustainable food source within the aquarium, as they may not readily accept prepared foods. They thrive in a peaceful tank setting with minimal competition for food.

Reproduction

In the wild, Ruby Red Dragonets form monogamous pairs during the breeding season. In the aquarium, if a pair is established, they may display courtship behavior and spawn. The eggs are pelagic, and raising the larvae can be challenging due to their small size and specific dietary requirements.

Habitat

Native to the Western Pacific, Ostorhinchus rubrimacula is typically found in shallow, coral-rich areas and sandy substrates. They are often observed hovering near the bottom, blending in with their surroundings to avoid predators.
