Zebra Danio Glofish are beautiful in a daylight tank as well, not just for a black light tank! They have the colors of saltwater fish!
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.
Eventually, in the blacklight alone nano, the corals didn't do well and he aborted that tank, but the blacklight plus a couple of normal lights did fine. No detriment to fish.
Here's my 90 gallon fish tank with the black light on.

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.Clownfish come in a variety of colors, including: orange, blue and yellow. Each clownfish features chunky white stripes outlined in thin black that glow under the soft luminescence of a black light. Clownfish are very active, so when the lights go down, you can expect their glowing parts to create a very unique look inside the tank, as they “clown around” their habitat. If you keep anemones for your clownfish, they may also glow under a black light.Black lights should not be used to heat or illuminate a fish tank. Fish need aquarium lighting that’s designed to provide the natural lighting they would receive in the wild. Because black lights are ultraviolet, it’s only safe to use them in small doses. A black light in the 315 to 380 nm range is the least harmful. Use the black light in small doses, such as an hour or so a day, to light up clownfish, neon tetras and other fishes with fluorescent, white or silver coloring.Received 48 Inch LED High Efficiency Lighting System With Lunar LEDs create a shimmering light that simulates natural sun-light, and perfect mixture of 10,000k Day-Light and 460NM Lunar diodes provide excellent color. This video NOT artificially enhanced & either are the Glo-Fish..This is the "lunar" (blacklight basically) setting. Soooo much prettier than my old cheap ones.
