I know they make some 'glofish kits' that have blacklights in them. Even the glofish site says not to leave it on all night, though. And the welfare of the fish is questionable by just the size of the tanks that are usually labeled as 'glofish' tanks, its all novelty to the sellers.
Black Lights for Aquarium Use? | Article | Aquarium Space
I've seen blacklights used in some Fish stores but usually only in glofish tanks so that buyers would be more anxious to get a brightly glowing fish. Which is a heated debate among many aquarists. Some sellers claim their glofish (which are actually zebrafish) are genetically mutated to glo, and some will even go as far as to say that the mutation is natural and bred by selection. Others state that their fish are simply injected with dyes and many buyers have no problem with this while others think its the most cruel thing in the world. Either way this isn't a fish I consider supporting the development and sale of if that is the case.

Most of these animals and decorations are brightly colored in any light but under special lighting, the colors will really glow. There are two main kinds of light that are used in these aquariums: “blacklights” and actinic lights. Knowing the difference between these two can play an important role in making your tank really stand out, as well as in keeping it healthy.
