danio

Small aquarium swimmer

A danio is a small freshwater fish native to South and Southeast Asia, popular in home aquariums for its hardiness and active swimming.

The zebrafish, used extensively in genetic research, is the best-known species.

Danios are schooling fish that do well in groups: I started my tank with a school of danios.
