🐟 Black Emperor Tetra (Nematobrycon palmeri (dark colour morph))
A Darker Colour Morph of the Classic Emperor Tetra • Elegant, Elongated Fins, Especially in Males • A Calm, Graceful Schooling Fish
📋 The Black Emperor Tetra is a darker colour morph of the Emperor Tetra, showing a greater proportion of dark patterning across the body than the standard form, paired with elegant, elongated fins, especially striking in males.
It comes from the Atrato and San Juan river basins of Colombia, naturally schooling with a calm, graceful swimming style. Every Black Emperor Tetra we ship is feeding well.
This is an active, easygoing schooling species and a reliable, hardy choice for a community aquarium. It does best kept in a group of 6-10, where its calm, distinctive presence stands out beautifully in a planted display. It reaches 4-4.5cm, so a 75L tank suits a school well.
