During a single month, an average of 1.8 million neon tetras with an estimated value of $ 175,000 are imported into the United States for the aquarium trade. With the exception of home aquarists and a few commercial farms that breed neon tetras experimentally, captive breeding on a commercial scale is nonexistent in the USA.

tetras capacity to change the color of its iridescent stripe in response to lighting conditions. In a light-adapted state it is blue-green, likewise in a dark-adapted state its color changes to indigo. This change is produced by guanine crystals in their cells that reflect light. The neon tetra grows to approximately 4 cm (1.5 in) in overall length.

A tropical sinking pellet is ideal, as most brands of these include natural color enhancers that bring out the color in neon tetras. Some frozen foods, including frozen blood worms, add variety to their diets.

The male is slender, and the blue line is straighter. The female is rounder, producing a bent blue line. Some aquarists say the females look plumper when viewed from above. However, the straightness of the line and the plumpness of the female might occasionally be due to the eggs she is carrying. A

Neon tetras are considered easy to keep in an aquarium of at least 10 US gallons (38 L; 8.3 imp gal) with a temperature range of between 72–76 °F (22–24 °C), a water pH of between 6.0 and 7.0, GH of below 10 dGH and KH of 1–2 dKH, and under 20 ppm of nitrate.
473:
Breeding neon tetras is considered to be difficult in home aquariums. However, it is becoming more common, with less than 5% of specimens currently sold in
America caught in the wild, and more than 1.5 million specimens imported to America each month from fish farms.

In the wild they inhabit very soft, acidic waters (pH 4.0 to 4.8) Ideal pH for aquarium is 7.0, but a range of 6.0 to 8.0 is tolerable. They can have a lifespan of as long as ten years, but normally just two to three years in an aquarium.

Generally the best 'treatment' is the immediate removal of diseased fish to preserve the remaining fish, although some occasional successful treatments have been performed that include fish baths and a "medication cocktail". The use of a

Neon tetras need dim lighting, a DH less than one, about 5.5 pH, and a temperature of 75 °F (24 °C) to breed. There also needs to be a lot of tannins in the water. Neon tetras are old enough to breed at 12 weeks.

They are shoaling fish and must be kept in groups of at least six, but will be more active in groups of eight to 12 or more. Neon tetras are best kept in a densely planted tank to resemble their native Amazon environments.
