GloFish were created in Asia by splicing the genes of zebra danios and hi-fin white skirt tetras and tiger barbs with phosphorescent corals and jellyfish. The fish were patented and licensed for sale in the USA several years ago once the FDA determined them to be safe for the environment. Though these fish do not actually glow in the dark they are truly fluorescent and will keep that bright color throughout their lifespan. When Glo fish breed their offspring have the same glow color. Spooky.
We offer all colors at an affordable price, including the new Glo shark.
