Anablepidae (Four-eyed fish) |
The Cyprinodontiformes is an order of ray-finned fish, also called the Microcyprini, and comprising mostly small, fresh-water fish. The Actinopterygii (the plural form of Actinopterygius) comprise the class of the ray-finned fishes. They are closely related to the Atheriniformes and are occasionally included with them. Atheriniformes, also known as the silversides, is an order of Ray-finned fish that includes the Old World silversides and several less-familiar Many popular aquarium fish, such as killifish and live-bearers, belong here. A killifish is any of various tiny Oviparous (egg-laying cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Poeciliidae is a family of fresh-water Fish which are live-bearing aquarium fish (they give birth to live young
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 the oxygen-rich water compensates for environmental disadvantages. Omnivores (from Latin omne all everything vorare to devour are species that eat both Plants and Animals as their primary

Reproduction
The families of Cyprinodontiformes can be divided into three groups: viviparous and ovoviviparous (all species give live birth), and oviparous (all species egg-laying). A viviparous Animal is an animal employing vivipary: the embryo develops inside the body of the mother as opposed to outside in an egg ( Ovipary Ovoviviparous Animals develop within eggs that remain within the mother's body up until they hatch or are about to hatch A live birth occurs when a Fetus, whatever its Gestational age, exits the Maternal body and subsequently shows any sign of life such as voluntary Oviparous animals are animals that lay eggs, with little or no other Embryonic development within the mother
