Cardinal Tetra
Cardinal Tetra
Paracheirodon axelrodi
Tetras are one of the best go-to fish for filling up some empty space in your aquarium. They are lively schooling fish that are quite active throughout the tank, creating a dazzling show of the metallic and bright colors they come in.
Tetras are peaceful and do best with other peaceful community fish, preferring to be in groups of at least 6 to feel secure.
Tetras max out at 2 inches, so they are best rated for tanks 10 gallons and upwards for a school of at least 6. Lots of natural foliage is recommended for the Tetra to weave through to create shady spots to rest and hide in.
Tetras will accept many forms of food, such as high-quality pellet and flake foods, thawed brine shrimp, and freeze-dried shrimp.
