Neon Tetra (Small)
The Neon Tetra is a Brilliant and the dazzling crown jewel of aquariums everywhere, the hardy little neon tetra fish was originally imported from South America.
Neon tetras originated from the clear water and blackwater streams and tributaries in the Orinoco and Amazon basin in Brazil, Columbia, and Peru. These are regions of blackwaters beneath dense forest canopies that allow very little light to get through. Neon tetras live in shoals mainly in the middle water layers and feed on worms and small crustaceans.

Ease of care
Newly set up tanks are not suitable for neon tetras because they will not tolerate changes that occur during the initial startup cycle. Only add neon tetras when your tank is fully mature and has stable water chemistry. Water should be soft and acidic for neon tetras, meaning a pH that is not above 7.5 and hardness of no more than 10 dGH. Blackwater extracts or driftwood are often used to darken the water, maintain an acidic pH, and soften the water.
In their natural habitat, neon tetras live in areas of dark water with dense vegetation and roots. Providing a habitat with plenty of low-light hiding places is important. Give them plenty of plants, including floating plants if possible, as well as hiding places such as rocks and driftwood. Driftwood will provide hiding places, and serve the dual purpose of softening and darkening the water. The dark substrate will help replicate the natural habitat that neon tetras feel most comfortable in. Some owners will put a dark background on three sides of the aquarium to achieve the desired low light habitat.
The food we recommend is tropical fish flake. Take care not to overfeed your fish.
A community fish, take caution not to house in an aquarium with fin-nippers.
Breeding / Sex
Neon tetras can be challenging to breed, due to the need for very specific water conditions. If you wish to attempt to breed them, set up a separate breeding tank. Water hardness in the breeding tank should be only 1 to 2 dGH, and pH 5.0 to 6.0. Use a sponge filter for filtration, and provide live plants. Spawning fish will often jump, so make sure the tank has a cover. Cover the sides of the tank with dark paper to reduce light in the tank. Water temperature should be kept between 72 and 75 F (24 C). Condition the breeding pair with feedings of live foods prior to placement in the breeding tank. When introducing the breeding pair to the tank, begin with no lighting at all. The next day, increase the lighting and continue to do so gradually to induce spawning. Spawning will generally occur in the morning. The male will embrace the female during spawning, who will release more than 100 eggs. The eggs are transparent and slightly adhesive and will stick to the plants. Remove the breeding pair as soon as the eggs are laid, as the parents will quickly eat them. Maintain low lighting as both the eggs and the fry are sensitive to light. The eggs will hatch in approximately 24 hours, producing very tiny fry that will feed off their egg sack for the next couple of days. Hatch rates are not high, so do not expect more than one-third of the eggs to result in viable fry. In three to four days the fry will become free-swimming and must be fed very small foods, such as infusoria, rotifers, egg yolk, or commercially prepared fry food. In a few weeks, they will be large enough to be fed freshly hatched brine shrimp. The fry will display adult coloration after about one month.
They can live to anything from 1-5 years in perfect conditions.
