Descripción de la especie

Melanotaeniidae species Melanotaenia praecox comes from 中北美洲. A schooling fish of open, sunlit water whose colours arrive with maturity, not in the shop tank. It swims in mid-water. Adults reach 6.8–9.9 cm. Groups of 6–8 minimum; larger schools calm them. Long tank, big group, steady water changes — colour follows within months. Maintain 27–30 °C at pH 7–8. Best suited to a keeper who can match its natural water.
