The neon tetra (Paracheirodon innesi) is a small freshwater fish native to the blackwater streams and tributaries of the Amazon basin in South America. They are known for their vibrant blue and red stripes that run the length of their body, making them a popular choice for aquarium enthusiasts. Neon tetras are social fish and should be kept in groups of at least six individuals. They prefer slightly acidic water with soft substrate and plenty of vegetation. Neon tetras are omnivorous and can be fed a varied diet of pellets, flakes, frozen or live foods. They are generally peaceful and can coexist with other peaceful fish species. Care should be taken to maintain water quality and avoid sudden changes in water parameters.
