Common name: Hawaiian ruby cardinalfish

General information

The Splendid Cardinalfish, also known as the Red Flame Cardinal, is a strikingly beautiful and peaceful marine fish that is a favorite among aquarists. Its vibrant red coloration, accented with a stark white line running from the head to the tail, makes it a standout in any reef or fish-only aquarium. This species is part of the Apogonidae family, which is known for its hardiness and ease of care.

Care

The Splendid Cardinalfish is a nocturnal species that prefers a dimly lit aquarium with plenty of hiding spaces. They are relatively easy to care for but do best in a stable environment with consistent water quality. A diet of small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood will keep them healthy and maintain their vibrant coloration.

Reproduction

Splendid Cardinalfish are mouthbrooders, with males taking on the responsibility of carrying the eggs in their mouths until they hatch. This fascinating reproductive behavior can be observed in the home aquarium if a male and female pair is established. The male will not eat during this brooding period, which can last for several weeks.

Habitat

Native to the Western Pacific, the Splendid Cardinalfish can be found in coral reefs and lagoons, often sheltering in caves or among the branches of corals during the day. They are typically found at depths ranging from shallow waters to about 20 meters deep.

Geographical distribution includes areas like the Great Barrier Reef, Indonesia, and the Philippines, where they contribute to the biodiversity of the reef ecosystem.
