Care

Red Sea Cardinalfish are relatively easy to care for, making them a good choice for both beginner and advanced aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These cardinalfish prefer dim lighting and a gentle water flow.

A varied diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their health and coloration. They are also known to accept high-quality prepared foods.

Reproduction

Like many cardinalfish, Apogon quadrisquamatus is a mouthbrooder. The male will incubate the eggs in his mouth until they hatch, providing protection from predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium.

Habitat

In the wild, the Red Sea Cardinalfish is typically found at depths ranging from 1 to 20 meters, often in association with coral outcrops or rocky substrates. They are social fish and can be found in small groups, which can be replicated in the home aquarium to observe their natural schooling behavior.
