GloFish Danio

GloFish Danios are a patented brand of genetically modified Zebra Danios, available in several fluorescent colors like red, green, orange, and blue. They possess the same hardiness and active nature as their wild-type counterparts, making them excellent for beginners. These fish are schooling, so they must be kept in groups of 6 or more to feel secure and display their best behavior. They thrive in a well-oxygenated tank with a moderate current. An interesting fact is that their fluorescence is hereditary and not a dye, and they will glow brightly under a blacklight.
