The Neon Tetra (Paracheirodon innesi) is a freshwater fish species native to the Amazon basin of South America. The Neon Tetra belongs to the Characidae family, and it is one of the most popular aquarium fish in the world due to its vibrant coloration. Amongst all varieties of Neon Tetras, there are certain ones that have been specifically bred for their hardiness and resistance against disease; these particular versions are known as Super Reds or Cardinal tetras. Super Red/Cardinal tetras have been selectively bred over time with only the healthiest individuals being reproduced in order to create a more resilient strain overall. These hardy variants of neon tetras can survive even in less-than-ideal water conditions, making them perfect for aquarists who don't want to be constantly fighting off illnesses caused by poor tank maintenance. In addition, they also tend to live longer than other types of neon tetras which makes them an ideal choice for those looking for longevity from their aquarium inhabitants!
