Rose Danio (Danio roseus) Care Guide
Danio roseus is a small Mekong-basin danio with a rosy lower body that gleams purple-blue, a peaceful but fast-swimming dither fish.
Overview
Danio roseus, the rose danio, was described by F. Fang and M. Kottelat in 2000. It is a slim danio that shows a rosy colouration along the lower part of the body and lower fins, gleaming purple-blue in sunlight, with blue, purple, silver and red tones overall. It is a peaceful but fast-swimming species.

Compatibility
It is peaceful but fast, like most danios, and is often used as a dither fish to help draw out shy species. Keep it in a group of six or more with other active fish of similar size.
