Danio rerio
Zebra danios are one of the hardiest, most energetic freshwater fish in the hobby. Their horizontal blue and silver stripes and constant darting motion add life to any aquarium. They tolerate a remarkably wide range of conditions, from cool subtropical to warm tropical temperatures, making them ideal for beginners. They are also the species used as the basis for GloFish.
