General information about Pajamas Cardinalfish
The Pajama Cardinalfish is a rainbow of vibrant shades. It features a yellowish-green face and bright orange eyes and a body that is silver-based, with a striking black scalar edge and an anterior dotted with orange polka dots. Although its striking coloration might make it stand out, Sphaeramia nematoptera has a tranquil nature that allows it to seamlessly blend into any saltwater aquarium. This aquarium fish ought to be housed in tiny groups in medium to large aquariums. Since the Pajama is a slow, methodical swimmer, it must be kept in a peaceful tank with other fish and given a myriad of hiding spots among the rocks or other plants. The majority of Pajama Cardinalfish will tend to conceal themselves within seagrass or in other plants. They may also hide against sea urchins with long spines. Similar to other schooling fish Pajama Cardinalfish create a strict hierarchy if kept in small groups within the aquarium. But, unlike other group fish that are social, this one belonging to the Apogonidae family is not using aggressiveness to gain the upper hand over other cardinalfish.
