Green Neon Tetra

A delicate, very small tetra with a luminous blue-green stripe and subtler red markings than a cardinal tetra. Adults generally stay around 2–3 cm.

Aquarium and care

Keep a substantial group in a mature, gently lit aquarium with fine-leaved plants and open areas. This species is best suited to stable warm, soft freshwater. Avoid sudden changes and immature aquariums; its tiny size does not remove the need for swimming space and excellent water quality.

Feeding

Use very fine prepared foods and tiny frozen or live foods. Watch feeding closely to ensure larger companions are not taking everything.

Temperament and tank mates

Best with other tiny peaceful fish or a carefully planned species display. Larger community fish may intimidate or eat them.
