Common name: Orbiculate cardinalfish

General information

The Pajama Cardinalfish, Sphaeramia orbicularis, is a small and peaceful marine fish that is popular among aquarists for its striking appearance and ease of care. It is characterized by its unique coloration, with a silver body, orange face, and a distinctive 'pajama' pattern of black spots and a vertical stripe on the posterior part of the body.

Care

Pajama Cardinalfish are hardy and adaptable, making them suitable for both beginner and advanced hobbyists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish are nocturnal and prefer dim lighting. They accept a wide variety of foods, including frozen and live meaty foods, as well as high-quality marine pellets.

Reproduction

In the aquarium, Pajama Cardinalfish can breed quite readily. They are mouthbrooders, with the male carrying the eggs in his mouth until they hatch. This fascinating reproductive behavior can be observed in a home aquarium if conditions are right and the fish are well-fed and stress-free.

Symbiosis

While not known for a specific symbiotic relationship like clownfish with anemones, Pajama Cardinalfish do benefit from living in a community tank with other peaceful species that provide a sense of security and natural environment.

Habitat

Pajama Cardinalfish are found in the Western Pacific, from Indonesia to the Great Barrier Reef. They inhabit coral reefs and lagoons, often sheltering in caves or among the branches of soft corals and gorgonians during the day.
