Pyjama Cardinal Tank Bred

Tank Bred Pyjama Cardinal, Sphaeramia nematoptera, are small and colourful fish that are popular in the aquarium trade, thanks to their relatively peaceful nature and use as a schooling fish.

Pyjama Cardinals have a striking and unique appearance, with their yellow heads and bright red spots near their tail. They have large eyes and a rounded snout, and their fins are a translucent yellow colour.

Tank Bred Pyjama Cardinal Ecology.

These fish are tank bred. In nature they occur in the Indo Pacific, around: Fiji, Great Barrier Reef, Java and Ryukyu Islands. They live in groups around corals in bays and lagoons. They use the structure as cover and are most active at night.

These fish are mouthbrooders. When breeding, males and females form distinct pairs. The female guards the male while he holds the eggs in his mouth. During which time, he will not be able to feed.

Pyjama Cardinals are unusual for a fish due to the amount of parental care they give to their offspring. Many fish do not invest any time in their eggs, once released. They produce a lot of offspring but with a high mortality rate. Cardinals however, produce small broods which have a higher survival rate thanks to their investment.

Sphaeramia nematoptera In the Aquarium.

It is important to have plenty of nooks or crannies where your Tank Bred Pyjama Cardinals can explore and feel at home.

These fish are mostly carnivores and do best when fed an enriched and varied diet. They will accept frozen mysis, brineshrimp and sometimes krill depending on the size. We enrich all our frozen food with garlic and vitamins. These are great for keeping fish healthy by providing them with the nutrition otherwise lost in frozen food. In doing so, these additives support their immune system and increase longevity.

Alternatively, Tank Bred Pyjama Cardinal will also eat live foods such as copepods, that can be cultivated in an attached refugium. Over time and with some persistence, it may also be possible to get these fish to accept high-quality pellet or flake.

We adapt all our Cardinals to aquarium life before they leave us. We focus on their health, and most are eating a good quality enriched frozen food before being offered for sale.
