Cosmic Blue Danio

Cosmic Blue Danio

The Asians created Glo® Fish 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.

Cosmic blue glo danios are hardy and their color never fades.
