Pajama Cardinal
Pajama Cardinalfish (Sphaeramia nematoptera)
The Pajama Cardinalfish is a peaceful, hardy schooling fish with a truly unique look — featuring a silver body, bold black mid-body bar, and a vibrant yellow face with red-spotted back half. Its quirky “pajama-like” pattern makes it a fun and colorful addition to reef and community aquariums.
Native to the Western Pacific, Pajama Cardinals are calm, easy to care for, and perfect for both beginners and experienced aquarists. They do well in groups and add constant, gentle motion to the tank.
