Killifish The word "killifish" is of uncertain origin, but is likely to have come from the Dutch "kil" for a kill (small stream). Although "killifish" is sometimes used as an English equivalent to the taxonomical term "Cyprinodontidae", some species belonging to that family have their own common names, such as the pupfish and the mummichog.
Killifish Killifish feed primarily on aquatic arthropods such as insect (mosquito) larvae, aquatic crustaceans and worms. It is reported by the killifish collector Rudolf Koubek that areas in Gabon where the streams lack killifish (due to pollution or other causes) are rife with malaria, which is spread by a mosquito. Some species of "Orestias" from Lake Titicaca are planktonic filter feeders. Others, such as "Cynolebias" and "Megalebias" species and "Nothobranchius ocellatus" are predatory and feed mainly on other fish. The American Flagfish ("Jordanella floridae") feeds heavily on algae and other plant matter as well as aquatic invertebrates. "Nothobranchius furzeri" needs much food because it grows quickly, so when food supplied is inadequate, bigger fish will eat the smaller fish.
Killifish Thanks to the genetic diversity of the species, killifish in the Eastern US have evolved within a relatively short period of time (50–60 years) resistance against levels of dioxins, PCBs, mercury, and other industrial chemicals up to 8,000 times higher than the lethal dose. Sequencing the genomes of the adapted individuals showed a common set of mutations among the pollution-tolerant fish, many of which helping to deactivate or turn off a molecular pathway responsible for a large part of the cellular damage caused by the chemicals.
Killifish A killifish is any of various oviparous (egg-laying) cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae and Valenciidae). Altogether, there are some 1270 different species of killifish, the biggest family being Rivulidae, containing more than 320 species. Because of living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. Like seeds, the eggs can be sent by mail without water. The adults of some species, such as "Kryptolebias marmoratus", can additionally survive out of the water for several weeks. Most killies are small fish, from one to two inches (2.5 to 5 cm), with the largest species growing to just under six inches (15 cm).
Killifish A small number of species will shoal while most are territorial to varying degrees. Populations can be dense and territories can shift quickly, especially for species of the extreme shallows (a few centimetres of water). Many species exist as passive tribes in small streams where dominant males will defend a territory while allowing females and immature males to pass through the area. In the aquarium, territorial behavior is different for every grouping, and will even vary by individuals. In a large enough aquarium, most species can live in groups as long as there are more than three males.
