The Cyprinodontiformes is an order of ray-finned fish, also called the Microcyprini, and comprising mostly small, fresh-water fish. They are closely related to the Atheriniformes and are occasionally included with them. Many popular aquarium fish, such as killifish and live-bearers, belong here.
Members of this order are notable for inhabiting harsh environments, such as saline or very warm waters, water of poor quality, or isolated situations where no other types of fish occur. They are typically omnivores, and often live near the surface, where they the oxygen-rich water compensates for environmental disadvantages.da:Tandkarpe de:Zahnkärpflinge eo:Dentokarpedoj fr:Cyprinodontiformes he:אידרונאים lt:Dančiakarpinės žuvys ja:カダヤシ目 pl:Karpieńcokształtne pt:Cyprinodontiformes ru:Карпозубообразные
