The Neon Tetra is a schooling fist and, as such, should always be kept with a community of 10 or so – they get lonely and sicken if alone. They prefer a somewhat dim environment so a few floating plants to filter the light is recommended as well as a dark substrate flooring. In addition, place plenty of plants on the bottom of the tank for hiding spots– but leave enough room for some “open” swimming. Be aware that during the night, - when your Neon Tetra is hiding and resting - it will “turn off” it's bright sparkling colors and it will look dull or dim. Light will gradually bring back their bright coloration.
The water temperature for Neon Tetras should be kept between 72F-78F degrees. Neon Tetras, in the wild are omnivores and eat a variety of foods including crustaceans, worms and small insects. They do love to eat, though, so be careful of over-feeding. Use a high quality flake food, with occasional supplements of daphnia, or brine shrimp for variety and they will do quite well. The pH balance of your tank should be from 5.5-7.5, which should be easy to maintain with such a nice span! Because their natural habitat has lots of rainfall, it is recommended that you replace your tank water frequently.
Neon Tetras, due to the wide range of waters in which they have been bred (whether in captivity or the wild), should be carefully acclimated into your tank to allow them plenty of time to adapt to their new home.
Neon Tetras are susceptible to – well – Neon Tetra disease. The official name is Pleistophora, which is the name of the sporozoan which causes the disease. There is no cure for the disease and the best way to avoid it is to prevent it from entering your tank in the first place. New fish should always be quarantined in a separate tank for a few days before being released into the main tank. The first sign of the disease are usually restlessness and a dull coloration. This is followed by cysts, which make the fishes body look lumpy. The Tetra will have trouble swimming and near the end the spine will become curved. By quarantining new fish you can help prevent the spread of this disease. Neon Tetra can also get Pleistophora from eating the bodies of dead fish – so be sure to remove any sick or dead fish as soon as possible.
