Though these fish do not actually glow in the dark, they are truly fluorescent and will keep that bright color throughout their lifespan. Orange glo tetras are great, bright schooling fish that do well in the community aquarium or a glo fish tank.

Care Guide
Tank setup: Give them a heater, a filter, plants and open swimming space. A dark substrate and background make the colors pop.
Feeding: Feed a quality flake or small pellet once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen foods like bloodworms and brine shrimp.
Tankmates: GloFish tetras get along with most peaceful community fish of similar size, such as other tetras, danios, rasboras, corydoras and livebearers. Keep them in a group so they don't nip the fins of slow, long-finned fish like bettas.
Good to know: GloFish colors look brightest under a blue or actinic LED light, but they are colorful under normal lighting too. Mixing colors in one school creates the best display.
