Overview
The Platinum Diamond Rummy Nose Tetra is a selectively bred form of the classic rummy nose, with a glittering silver-white body and the same vivid red head and black-and-white banded tail. The wild species comes from blackwater rivers of the Orinoco and lower Amazon. It suits peaceful community and planted aquariums where a tight, synchronised shoal shows at its best.

Final Notes
The red head is a live water-quality gauge: it fades when conditions slip, so add this variety only to a well-established aquarium and keep nitrate low with regular water changes. Colour also dulls in alkaline water. Egg-scattering spawns take place in the evening among fine-leaved plants; females are noticeably rounder than males. Dim lighting, driftwood and leaf litter bring out the platinum shimmer.
