GloFish®. The most colorful pets for the most dazzling aquarium

Experience the Glo!®

GloFish® fluorescent fish add an alluring array of brilliant colors to any aquarium. Neither injected with dye nor painted, GloFish get their stunning color from a fluorescence gene, and are best viewed under a blue light.

How to get your Glo on. Just starting out? Here’s what you need to do.

1. Set up your Tetra GloFish® Aquarium.
Kit contains aquarium, LED lighting, filter and filter cartridge. Some kits may also include a heater.

2. Add GloFish® brand décor and accessories

Use Tetra® Water Conditioner and SafeStart® to remove chemicals and establish healthy bacteria. Make sure water is between 72 and 80 degrees.

4. Add GloFish®.
Let GloFish® acclimate to their new aquarium by placing their sealed bag in the tank for 15 to 20 minutes. Next, release them and enjoy the glo show!
