Neon Tetras originate from the clear water and blackwater streams in the Amazon and Orinoco Basin in Brazil, Peru and Columbia. They should be kept in schools of at least six or more, and they do well in community tanks, as long as their tank mates are non- aggressive or large.
The Neon Tetra is recognised by its bright blue neon stripe, which is believed to make them more visible to each other in blackwater conditions.
