Common name: Ishigaki Cardinalfish

General information

The Ishigaki Cardinalfish, scientifically known as Ostorhinchus ishigakiensis, is a small and colorful marine fish that is a member of the family Apogonidae. This species is not as common in the aquarium trade as some other cardinalfish, but it is gaining popularity due to its striking appearance and peaceful demeanor. The Ishigaki Cardinalfish has a pale body with distinctive dark bands and spots, which make it a visually appealing addition to any reef or fish-only aquarium.

Care

Ishigaki Cardinalfish are relatively easy to care for, but they do require a stable and well-maintained aquarium environment. They thrive in groups and should be kept in a small school of at least five individuals to promote natural behavior and reduce stress. These fish prefer a tank with plenty of hiding places among live rock or dense vegetation. They are nocturnal feeders, so offering food after the lights go out can mimic their natural feeding habits.

Reproduction

Like many cardinalfish, the Ishigaki Cardinalfish is a mouthbrooder. The male will carry the fertilized eggs in his mouth 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

Ostorhinchus ishigakiensis is native to the Western Pacific, particularly around the Ryukyu Islands and Taiwan. They are typically found in shallow, coral-rich areas and lagoons. In the wild, they tend to stay close to the bottom, often seeking refuge among corals and rocky substrates.
