Dario dario (aka Scarlet Badis, Scarlet Gem Badis) are one of my favorite species of freshwater fish. They are ideally suited to low-tech nano tanks. The males have a beautiful coloration and pattern, primarily red with blue vertical stripes. Submissive males can have drab colors, and females are shades of grey. They are a fascinating, shy little micropredator.
