The fascinating GloFish has been genetically altered to give off a bright neon glow. The genes of this Zebra Danio have been altered with the genes of a certain anemone that features the illuminescence, and that is how the GloFish came about!
The Electric Green GloFish is bright yellow-green. It has faint silver-gold horizontal stripes.
The GloFish is just as hardy as a regular Zebra Danio and also features the same bluish striping. They are an active fish that will hang out around mid-water or upper water level. They are great for community tanks. Feed them a varied diet of flake, small pellet, and occasional small-sized frozen food.
The glowing coloration of the GloFish 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.

This fish's arrival size is 1 inch in length. A really sweet schooling fish and the awesome factor is you can mix and match danios if their the same size. The danios swim back and forth at the top of the aquarium.
