GloFish can be a vibrant and exciting addition or focus of a home aquarium! GloFish are now available in a variety of species including danios, barbs, tetras, sharks and bettas, and care should be provided as it would for their natural-colored species. Aquariums for GloFish should be a minimum of 5 gallons, however it is best to remember the "1 inch of adult fish per gallon" rule and choose an aquarium large enough to be suitable for the species of GloFish you choose, especially with those that are schooling fish.
Although these fish are genetically enhanced variations of their normal-colored counterparts and can be housed with compatible species, their colors will be the brightest when housed in an aquarium dedicated to enhancing their colors. GloFish aquariums are often mostly blacked out with neon accents, plants and decor and blue or black lights to enhance the glowing color of the fish.
