Platy fish are both active and colorful. They come in many different varieties and even species. These platies in particular have a yellow-orange body with black markings/spots and an incredible blue sheen that is hard to capture on camera. Some may have more black on them than others. A good ratio of both sexes will be sent if you order multiple fish. Platies make an excellent choice of fish for those starting out in the aquarium hobby because of their hardiness. They should be able to do well in cooler temperatures, being able to dip down to a temperature of 72F. Like other livebearers, they need a good amount of calcium in their system, so they do best in harder water.
