The GloFish Tetra is the latest selective-breeding development from the aquaculturists that bred the popular GloFish Danio, a variant of the Zebra Danio (Danio rerio). The genes of this tetra have been altered with the genes of certain anemones, corals or jellyfish that features the illuminescence, giving the tetra a bright, permanent neon hue that is much safer to the fish than the outdated methods of dyeing or color-injecting fish. The original Electric Green GloFish Tetras are bright neon yellow-green in color; two new colors - Moonrise Pink and Sunburst Orange - were released in May 2013 and the Galactic Purple GloFish Tetra was released in November 2013. Two more colors - Starfire Red and Cosmic Blue were released in September 2014.

GloFish Tetras were created from the popular White Skirt Tetra, (Gymnocorymbus ternetzi). They are a schooling type of fish that generally need a group of at least 3 to be more comfortable in a home aquarium. As they reach a size that is a little larger than the other tetras, tankmates should be chosen accordingly. Smaller fish may be chased or nipped at if housed with these fish in a small aquarium. The will accept most flake and pellet food and should be fed once a day with a variety of these foods to help them keep a healthy immune system. All in all they are a very hardy aquarium fish and are excellent for beginners who are just learning about keeping aquariums.

The glowing coloration of the GloFish Tetra will not fade or change - it is within their genetic structure and will actually be passed on to their offspring should they spawn. To see them "glow" at their best, keep under blue "actinic" lighting. The colors will be bright under white lighting but will not "glow" as brightly.

Awesome coloration with other GloFish


I got four of the Purple versions of this GM fish to go with the other twelve that I have had (green, yellow and pink) and their addition really made the tank pop. I think the fourth color created a new depth. In any case my Holiday party guest really remarked on how cool the tank was.
