Common name: Cardinalfish

General information

The Blacktail Cardinalfish, scientifically known as Apogonichthyoides melas, is a small and peaceful marine fish that is well-suited for reef aquariums. This species is known for its striking appearance, with a silver body, black tail, and a distinctive spot at the base of the caudal fin. They are nocturnal by nature and tend to hide during the day, becoming more active at night.

Care

Blacktail Cardinalfish are relatively easy to care for, making them suitable for both beginner and experienced aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish prefer dim lighting due to their nocturnal habits. A varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

In the wild, Blacktail Cardinalfish are mouthbrooders, with males incubating the eggs in their mouths until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium, where successful breeding can occur if the environment is stable and stress-free.

Habitat

Apogonichthyoides melas is native to the Western Pacific, where it is typically found in coral reefs and lagoons. They prefer sheltered areas with plenty of live rock or coral to hide among during the day.
