Rasboras & Danios: Complete A-Z Species Directory

Rasboras and danios are among the most popular freshwater community fish in the aquarium hobby. These small, colorful schoolers belong to the family Danionidae, which was formerly lumped under the broader Cyprinidae family before taxonomists split it out. The common names “rasbora” and “danio” span multiple genera — from the tiny Boraras micro rasboras to the larger, fast-swimming Devario danios — so the group is more diverse than most hobbyists realize.

Whether you are stocking a 5-gallon nano planted tank or a 55-gallon community setup, there is a rasbora or danio that fits. These fish are generally peaceful, hardy, and easy to care for, which is why they include some of the most widely kept aquarium fish in the world. The celestial pearl danio, harlequin rasbora, and zebra danio alone account for millions of fish sold every year. This A-Z directory covers every species we have profiled at Aquarium Store Depot, plus additional species we plan to cover soon. Click any linked name to read the full care guide.
