Tropical fish

Tropical fish, any of a variety of marine and freshwater fish native to the tropics, but particularly those valued for use in aquariums because they are ornamental, small, and able to reproduce quickly and easily. The tropical fish most commonly found in home aquariums are guppies and other freshwater fish of the Poeciliidae family, bearing live young (rather than eggs). Some other popular aquarium fish are cichlids, which are egg bearing, and clown-fish, a saltwater species. Tropical fish range in size from 1–12 in (2.5–30 cm) and generally eat food made from grains, as well as insects, fish, aquatic plants, and dried fish.
