Artificial vs. Natural beauty... Becoming a common sight in pet stores - Glo-fish. The fish were genetically altered with a protein gene originally injected from jellyfish to make them fluorescent in an aquarium fitted with black light. Welcome to the future.

Come to think of it, as per my post above, I'm guessing that actinic lights (thought they serve another definite purpose apart from this) may well have been the aquarist's answer to the black light... They certainly do the trick. black light aquarium - Google Search

With the growing popularity and availability of fish like and decorations like our own line, “glow-in-the-dark” and fluorescent aquariums are becoming more and more common. 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. For this blog, we will be focusing in general terms only for community aquariums. Aquarium with invertebrates and corals will have different needs since their light requirements are much more specific and extensive.Making the choice between using actinic or blacklights for your glowing aquarium depends on when or how you would like to view it. and are both available with a variety of actinic and blacklight option. Both actinic lights and blacklights make things glow when the light they produce is reflected off of the fluorescent pigments in the object, whether this is light we can see (actinic) or light we can’t (blacklight). These pigments could be in the artificial coloration of an ornament or plants, or in the proteins or cells of a living creature, either artificially or naturally. Many plants and animals that we don’t think of as “glowing” have pigments that are fluorescent under the ultraviolet range. This can help them to blend in or stand out to other animals that can see this range that we can’t. Fish like GloFish have been enhanced with proteins from these fluorescent creatures at their embryotic stages so they can share in these glowing traits.The colors we see around us come from the light’s wavelength, measured in Terahertz (THz) or nanometers (nm). Most people can see light ranging from about 700nm (reds) to about 400nm (purples). Blacklights and both produce light from the bottom of the visible light spectrum (the BIV in ROY G BIV). Most actinic lighting for aquariums has a wavelength of about 420-460nm. The higher end of this range (460nm) produces a more blue color light, while the color shifts to purple approaching the lower end (420nm). This type of lighting is still well within what we are capable of seeing. “Blacklights” emit a light below what we as humans are able to see known as ultraviolet or UV light. Yes, this is the same UV light that we wear sunscreen to protect ourselves against! UV lighting is separated into three major ranges. Blacklight bulbs are UV-A bulbs (315-400nm), the spectrum which causes our skin to tan. For comparison, the UV Sterilizers popular in aquariums for eliminating algae, diseases and parasites are UV-C bulbs (200-280 nm), a destructive spectrum that is mostly filtered out by Earth’s atmosphere and the UV-B range in between is the more damaging rays from the sun that causes sunburn and other harmful conditions.Incase you do have a blacklight that actually does produce UV--UV is deadly to pretty much all forms of life. It can do serious damage to living tissues. On this planet, we have a layer of ozone (O3) in our atmosphere, that absorbs a very significant percentage of the UV radiation from the sun. With out it, life wouldn't have developed (well, life as we know it anyway) on Earth. There is a reason that UV lamps are used to sterilize aquarium water after all.
