Diamond Tetra

A shimmering tetra whose scales develop a sparkling appearance as the fish matures. Adults reach roughly 5–6 cm, and mature males often develop longer fins.

Aquarium and care

Keep at least six to eight in a mature planted tropical aquarium with open swimming space. Stable clean water, moderate flow, and some shaded cover encourage confident behavior and coloration. Juveniles may look less reflective than mature fish.

Feeding

Feed quality small prepared foods and rotate suitable frozen or live foods. A varied diet supports growth and condition without overfeeding.

Temperament and tank mates

Generally peaceful with similarly sized community fish. Avoid persistent fin nippers and provide enough space for mild display and chasing within the group.
