Longfin red Color Danio (Brachydanio Rerio)

Fiery, flowing, and full of energy — the Longfin Red Danio (Danio rerio var.) combines the classic hardiness and energy of the Zebra Danio with a vivid red to orange-red body and dramatically elongated, flowing fins. The longfin gene transforms this beloved fish into a striking, elegant schooling fish that brings warm colour and graceful movement to any community aquarium.

Overview

Appearance

The Longfin Red Danio displays a vivid red to orange-red body with horizontal striping and a warm metallic sheen. The longfin gene extends all fins dramatically — the caudal, dorsal, and anal fins flow gracefully, giving the fish an elegant, veil-tail appearance as it moves through the water. A school of these fish creates a warm, fiery, flowing display that is both dynamic and visually striking against green planted backgrounds.
