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: Long flowing fins are easy targets for fin-nippers, so avoid tiger barbs and serpae tetras. GloFish colors look brightest under a blue or actinic LED light, but they are colorful under normal lighting too.
