Pajama Cardinalfish

The Pajama Cardinalfish is a striking nocturnal species prized by experienced aquarists for its distinctive two-tone coloration—deep red upper body contrasting with silvery-white lower half. Native to Indo-Pacific reef environments, this small cardinalfish reaches approximately 3-4 inches and thrives in established tanks with moderate lighting and plenty of hiding spaces among rockwork and coral. Naturally gregarious, they perform best in small groups, displaying fascinating schooling behavior during twilight hours. Feed quality meaty foods including mysis shrimp and small crustaceans. Ideal for reef aquariums with peaceful tankmates, they require stable water conditions and moderate water flow. A captivating addition for those seeking unique nocturnal activity and refined aesthetics.
