Glofish Supplies

GloFish are genetically enhanced with bright, beautiful colors that make an attractive fish that will help brighten up your home aquarium. GloFish come in several different species—including danios, barbs, and tetras—but all are active, schooling fish that will inhabit all areas of your aquarium. As these are schooling fish, a minimum of a 5-gallon aquarium is recommended, however starting with the largest aquarium possible is ideal to ease maintenance of water parameters, as well as keep larger schools of fish.
