A separate breeding tank could be set up especially for breeding, however. Breeding Neon tetrasĪlthough bred commercially, Neon tetras are not commonly bred in the home aquarium due to the fact that the eggs are so small, they get eaten by other fish, and are sensitive to light. In nature eggs fall between roots and leaves and are sensitive to light, requiring dark for proper development. Neon tetras are egg scatterers, coming together to spawn but taking no extra care for their tiny eggs and fry.

Live plants do aid water quality however and can provide shade for Neons as well as providing somewhere to take cover and breed. Plastic or live plants can be used but are not essential. Neon tetras don’t actually glow in the dark, but that iridescent blue colouration has highly reflective scales, further contrasting the deep red on the tail.įor a natural look fit a black background and decorate the tank with sand, leaves and wood. Lighting can be subdued and their colours may even intensify in low light. Neons can be kept in aquariums upwards of 40cm in length, and need a heater for warmth and a filter to break down their waste. They live in number in the wild and need to be kept in shoals of ten or more in the aquarium. Neon tetras inhabit small forest streams where their bright colours enable them to locate each other in the gloom as well as dazzling and confusing any would-be predators. Neon tetras belong to the family Characidae, which includes Piranha and huge, walnut-eating Pacu, but in general, tetras are small, peaceful schooling fish inhabiting rivers and streams in South America and Africa. Native to Peru, Colombia and Brazil these tiny colorful fish reach a maximum size of just 3cm in length, making them suitable for smaller tropical aquariums. They can be seen in virtually every tropical fish shop around the world and sell in their millions every year. Neon tetras are small tropical freshwater fish with a bright red stripe and light blue electric colouration.
