The Green Neon Tetra is a beautiful, peaceful species is best maintained in groups of 6 or more fish in a softwater aquarium. Tankmates, if desired, should consist of small fish only, and which are of a similar disposition. Green Neon Tetras appreciate rooted and floating plant cover to help diffuse some of the light. Specimens offered for sale in the trade are almost all wild-caught from their natural blackwater environment which is surrounded by overhanging vegetation from the rainforests, hence the need for dappled light to be provided. Peat filtration is highly recommended. May also be seen on sale as the False Neon Tetra.
Flake, micropellets, small frozen foods such as daphnia, baby brineshrimp and cyclops.
Difficult. Best results are obtained when groups, rather than pairs, are added to the spawning aquarium. Each female can lay up to 130 eggs. The water must be very soft and acidic, and plenty of Java moss (or spawning mops) placed on the bottom of the tank to collect the eggs. The adult fish should be removed from the aquarium once spawning has ceased in order to prevent predation on the eggs. The tank should be kept in darkness as the eggs are light sensitive. These eggs should hatch within 24 hours. Once free-swimming, the fry should be offered infusoria.
