Neon Tetra

A classic small schooling tetra with an electric-blue stripe and red coloration on the rear half of the body. Adults usually reach around 3–4 cm.

Aquarium and care

Provide a mature aquarium with plants, shade, and an open swimming area. Keep at least eight together. Moderate tropical temperatures around 21–25°C suit neons better than consistently hot conditions. Soft to moderately hard, stable clean water and routine water changes help the school thrive.

Feeding

Offer fine flakes or micro pellets plus small frozen foods. Feed little and often enough for the whole group without leaving food to decay.

Temperament and tank mates

Good companions include peaceful small fish with similar temperature needs. Avoid large predators and persistent fin nippers.
