Common name: Longspine cardinalfish

General information

The Whipfin Cardinalfish, scientifically known as Apogon doryssa, is a small and peaceful marine fish that is well-suited for community aquariums. Its slender body and distinctive whip-like caudal fin make it a unique addition to a reef tank. The Whipfin Cardinalfish is nocturnal and tends to be shy during the day, often seeking refuge in rockwork or coral branches.

Care

Whipfin Cardinalfish are relatively easy to care for, but they do best in a well-established aquarium with stable water conditions and plenty of hiding places. They are a schooling species in the wild, so keeping them in groups will help them feel secure and display natural behaviors. These fish are carnivorous and should be fed a varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

Like many cardinalfish, Apogon doryssa is a mouthbrooder. The males incubate the eggs in their mouths until they hatch, providing protection from predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium if the fish are well cared for and feel secure in their environment.

Habitat

Whipfin Cardinalfish are found in the Indo-Pacific region, typically in coral reefs and lagoons. They prefer areas with moderate currents where they can hover and feed on plankton or small crustaceans. In the wild, they are often found at depths ranging from shallow waters to about 30 meters deep.
