GloFish®, Cosmic Blue® Danio

What do you get when you cross one of the easiest-to-care-for freshwater fish with the brightest new breakthroughs in the aquarium hobby? The perfect starter fish for your desktop, kid’s room, or specialty setup!

Fluorescent GloFish® are the first designer-bred Danios (Zebra Fish) to come in five neon colors: Starfire Red®, Electric Green®, Sunburst Orange®, Cosmic Blue®, and Galactic Purple®. GloFish® are not dyed and their color, which is inherited from their parents, does not fade!

Original generations of GloFish® were genetically enhanced as embryos to help detect environmental pollutants and advance scientific research. Now every generation of GloFish® is born with its amazing color! The brilliant hues are produced by a fluorescent protein gene which occurs naturally in some marine organisms.

Keeping GloFish® is as easy as keeping Danios. For best care, keep this peaceful fish by themselves in small aquariums or in small schools with equally non-aggressive fish. Since they are omnivores, feed GloFish® a varied diet of flake and frozen foods.
