The Cardinal Tetra brings delicate beauty to any home freshwater aquarium. It has a bright blue stripe contrasted by a lower red stripe that runs the entire length of its body. This coloration differs from its cousin, the Neon Tetra, which has a red stripe that runs only halfway down the body. Equally as peaceful as Neon Tetras, Paracheirodon axelrodi will school together for a brilliant display of activity and color to dress small to large aquarium systems.
Recommended Tank Parameters:
Minimum Tank Size: 30l
Lifespan: Up to 5 years
Habitat: Cardinal tetras adapt to a wide range of aquarium setups but they perhaps looks best in a heavily-planted set-up or natural-style arrangement comprising a sandy substrate plus some driftwood roots and branches.
Diet: Cardinal tetras feed readily on flake foods, granulated and small pellets, and many frozen and live foods including bloodworm, brine shrimp, black mosquito larvae and Daphnia.
Temperament: Generally peaceful making it an ideal resident of the well-researched community aquarium. It’s perhaps best-maintained alongside similarly-sized characids, gasteropelecids, lebiasinids, smaller callichthyid or loricariid catfishes and non-predatory, small-to-medium-sized cichlids. Try to keep a group of at least 8-10 specimens, include other schooling fishes to provide security, and you’ll be rewarded with a more natural-looking spectacle.
