The Neon Tetra (Paracheirodon innesi) is a species of characin actinopterygii fish originally from the west of South America. It is a fish much appreciated in aquaria due to its eye-catching colour and its movements in shoals, bringing movement and life to any aquarium.
Within its same genus is a very similar species, also popular with aquarium enthusiasts: the Cardinal Tetra (Paracheirodon axelrodi). Of all these fish found in aquaria, the Neon Tetras are bred 95% in captivity for their subsequent trade, for the most part in Hong Kong and other locations of Southeast Asia, while the Cardinal Tetras are caught almost 99,9% in their natural habitat. It is one of the species most appreciated by those seeking to recreate an Amazonian biotope.
