Neon tetra facts for kids
The neon tetra has a light-blue back over a silver-white abdomen. The fish is characterized by an iridescent blue horizontal stripe along each side of the fish from its nose to the base of the adipose fin, and an iridescent red stripe that begins at the middle of the body and extends posteriorly to the base of the caudal fin. Rarely, they develop a dark olive-green sheen lining on their backs. The fish is partially transparent (including fins) except for these markings. During the night, the blue and red become gray or black as the fish rests—it reactivates once it becomes active in the morning. It grows to approximately 3 cm (1.2 in) in overall length. Sexual dimorphism is slight, with the female having a slightly larger belly, and a bent iridescent stripe rather than the male's straight stripe. They have recently become available in a long-fin variety.
In the aquarium
Neon tetras are sturdy, cheap and easy to look after. They are schooling fish and like to be kept with other neon tetras. They can also be kept in community tanks with other peaceful fish. They like to live in a water temperature of around 20–26°C.
