Care

Transparent Cardinalfish require a well-established aquarium with plenty of hiding places among live rock or soft corals. They are a schooling species in the wild, so they do best when kept in small groups in captivity. These fish are nocturnal and may be shy during the day, so providing dim lighting or shaded areas can help them feel secure. They accept a variety of foods, including small frozen or live foods like brine shrimp and mysis.

Reproduction

Like many cardinalfish, Pseudamia gelatinosa is a mouthbrooder. The male carries the eggs in his mouth until they hatch, providing protection from predators. Breeding them in captivity can be challenging due to their specific requirements and the need for pristine water conditions.

Habitat

Transparent Cardinalfish are found in the Indo-Pacific region, typically in coral reefs and lagoons. They prefer sheltered environments with plenty of hiding spots and can be found at depths ranging from shallow waters to about 20 meters deep.
