Home ranges of these animals in the wild hav not been reported. ( "Aquaria Central", 1997 "Paracheirodon simulans (Green Neon Tetra)", 1998) Small localized migrations may take place in response to changing water levels. These are also thought to be the schools within which they mate. They are typically found in schools of 6 fish or more. There is little information on the behavior of P. The longevity of green neon tetras has not been reported. ( "Aquaria Central", 1997 Binohlan and Casal, 2003) Adult tetras may even eat their eggs and larvae. Once eggs are laid, adult tetras do not provide any further parental care. In captivity these fish can reproduce at any time of year. Breeding season Breeding season in the wild is influenced by water levels, generally occurring during rainy seasons.Breeding interval Green neon tetras breed every few weeks.gonochoric/gonochoristic/dioecious (sexes separate). ![]() Eggs are typically laid during the rainy and wet seasons when water levels are higher. Generally, eggs are left under canopies to ensure they hatch. The larvae of these fish are sensitive to ultraviolet radiation, so are restricted in the areas in which they may lay their eggs. These fish tend to breed every few weeks. Female neon tetras lay approximately 130 eggs on the substrate. Information on reproduction in tetras comes from specimens housed in aquaria. Paracheirodon species generally spawn in schools, although single males and females may become closely associated while the female releases her eggs and the male releases his sperm. axelrodi generally develop within 24 to 30 hours of fertilization. The pattern of development in these animals has not been characterized. Range length 2.5 (high) cm 0.98 (high) in.These fish can grow to a maximum overall length of approximately 2.5 cm. The lateral blue-green stripe extends to the base of the caudal fin. Green neon tetras appear similar to neon tetras, Paracheirodon innesi, although they are smaller and the red patch on the lateral body is less pronounced. Because these jungle waters are typically shaded by overgrown trees, when keeping green neon tetras in captivity it is best to duplicate this natural shading by making the sides and bottoms of the aquarium dark. Temperatures in these waters range from 72 to 82 degrees F. They have been found in northwest Brazil in the River Negro to Colombia and Venezuela in the upper Orinoco River basin. Paracheirodon simulans is mainly found in black water rivers of the South American tropics. ![]() ( "Aquaria Central", 1997 Binohlan and Casal, 2003 "Paracheirodon simulans (Green Neon Tetra)", 1998 Robins, et al., 1991) These fish, which are commonly called green neon tetras, are found in northwest Brazil to Colombia in the River Negro, and in Venezuela in the upper Orinoco River basin. Paracheirodon simulans is native to the neotropical region.
