Curator's Note

One of the amazing aspects of this fish is that they have been known spawn in captivity. It is difficult to tell male from female unless the male is holding fry in its mouth. Cardinalfish are mouth brooders and for several weeks a male cardinal will not eat while it is carrying babies. Swelling in the jaw, lack of appetite are obvious signs. If you watch closely, you may even see little eyeballs staring out when he aerates the eggs with water. Most of the fry might not survive, especially if in a densely populated aquarium.

Other Common Names

Spotted Cardinalfish, Polka-dot Cardinalfish

Description

The Pajama Cardinalfish is a very oddly colored fish. It is perhaps the spots that give it the appearance that it might be hanging about in it’s ‘jammies’. Like the other Cardinalfish, it is a very hardy fish. It’s hardiness makes this an easy fish for the beginning aquarist to maintain. Cardinals are nocturnal by nature and will spend most of their time in the shadier areas of the aquarium and will come out after dark. They will learn to adjust to the brighter lit aquarium in time. Unlike many other Cardinals, this particular fish prefers to be in groups and schools. It will live peacefully with other non-aggressive fish.

Diet

Feed frozen small meaty foods or finely chopped prepared foods. Cardinalfish eat small fishes and mobile crustaceans in the wild. If your Cardinalfish appears to not eat, try feeding after the aquarium lights turn off. Many Cardinalfish have nocturnal tendencies and will prefer to be fed after the lights go out in the aquarium.
