Saltwater Fish
Pajama Cardinalfish.
A charming, slow-moving cardinalfish in mismatched 'pajama' patterns — yellow face, dark band, and polka-dot tail. Peaceful, reef-safe, and beginner-friendly; it's happiest in a small group hovering among the rockwork of a 30-gallon-plus reef.

Good tank mates
The pajama cardinalfish is peaceful, reef-safe, and community-friendly, making it a calm pick alongside clownfish, firefish, gobies, and other non-aggressive reef fish. It is happiest kept in a small group and won't bother corals or most invertebrates, though it may eat very tiny ornamental shrimp; avoid housing it with aggressive or fast fish that will stress this slow-moving species. It schools loosely and adds quiet movement to a peaceful tank.
Good to know
Like other cardinalfish, the pajama cardinal is a paternal mouthbrooder, with the male holding and protecting the fertilized eggs inside his mouth until they hatch.
