Why not use fish as night lights?

Light up your bedroom with sparkling, fluorescent angelfish!

in 2010, a Taiwanese company genetically modified angelfish (Pterophyllum scalare) and convict cichlid (Cichlasoma nigrofasciatus) for the first time to create brilliant, green-glowing fish. 

Now it is possible to get these little fellows as pets!

And, really, who doesn't want a fish disco in their bedroom?
