The 24k Gold Guppy is a stunning color variation of the very popular livebearer species. They really shine like gold in the aquarium, and attract a lot of attention from anyone passing by their tank. These are U.S. bred guppies that are ready to adapt to your water. There is a chance that these fish carry the ribbon gene (extended caudal and anal fins), as this strain originally comes from 24k Gold Ribbon Guppies. Guppies are one of the most popular fish in the aquarium hobby. They are gorgeous fish that come in so many different strains and colors. Like other livebearers, they need a good amount of calcium in their system, so they do best in harder water.
