Cardinal Tetra, Paracheirrodon axelrodi, is one of the most famous and popular species in the hobby. It is a truly beautiful fish and should be on everybody's must-have list. The cardinal tetra has the striking iridescent blue line which runs across its upper body and the vivid red line running below it. A large group of cardinal tetras, and the combination of the iridescent blue and vivid red they display, produces a stunning glittering effect in an aquarium and it is a sight to behold. The cardinal and neon tetra look similar but the neon tetra's red coloration extends only about half its body length.
Care & Maintenance
Cardinal Tetras are small characins and belong to the Characidae family. It is native to the Orinoco River in Venezuela and the northern tributaries of the Rio Negro in Brazil and western Colombia. In nature, these fish are often found in tannin-stained and slow-moving waters, seeking shelter among aquatic plants, tree roots, and branches. They will tolerate a wide range of aquarium conditions and are particularly suited for community tanks because of their small size and peaceful temperament. They must be kept in groups of at least 6 individuals and preferably more.
|Max Size:||2 inches|
|Water:||75 - 84 F; pH 5.5 - 7.5|

In aquariums, cardinal tetras will appreciate well-planted tanks with open spaces. Placement of additional aquarium decorations such as driftwood and rocks is recommended. These aquascape features will provide shelter and make the fish feel safe. Cardinal tetras are shoaling fish and the larger the number of the individuals the more striking their visual impact will be in the aquarium.
Cardinal tetras can be kept with many other peaceful fishes, including discus, dwarf cichlids, corydoras catfish, plecos, and many other community fish. They will readily accept a variety of foods, including flakes and small pellets..
