The Neon Tetra is often described as the jewel of the aquarium hobby. It is easy to see why it is one of the most popular freshwater tropical fish. With their iridescent blue bodies and bright red tails, Paracheirodon innesi creates an exciting splash of color in any aquarium, especially when kept in schools of six or more.Native to the clear water streams of South America, the Neon Tetra prefers densely planted systems with plenty of low light areas to hide. To best recreate its natural habitat, place rocks and driftwood amongst the plants for added areas of refuge. However, the Neon Tetra will tend to swim or remain suspended in the water column in schools to create a breathtaking display of color. Extremely peaceful, the Neon Tetra should be kept with similarly non-aggressive tankmates of a similar size.
