A very beautiful group of fish which can be quite hard to find.
Egg laying toothcarps. (Compare Livebearers). There are two types of Killifish, the Annuals and the non-Annuals. Annual Killifish inhabit temporary bodies of water that completely dry up during part of the year. These fish have a short lifespan and rapid growth rate, reaching maturity within a few months. They lay eggs that remain dormant until the conditions are favorable for hatching, when the rainy season returns. Their eggs are incubated by aquarists in a special way to imitate this (see Peat). Non-annuals have a longer lifespan, but most also have the ability to lay eggs that can survive a short dry season.
small mostly marine warm-water carp-like schooling fishes; used as bait or aquarium fishes or in mosquito control
Fundulus heteroclitus, or the killifish, is a small shallow-water minnow common along the Atlantic coast. The egg of the killifish is tough and transparent which allows easy laboratory manipulation and observation of embryo development without undue stress on the developing embryo. Killifish embryos were first flown on the Apollo Soyuz mission to study the development of the vestibular system.
A family of African freshwater fish that only have a life span of one year.
This family of small freshwater fish is quite rare in the fish hobby. They live only one year, laying eggs that can then survive harsh conditions.
A very beautiful group of fish in the family, Cyprinodontidae.
A killifish is any of various small, mainly oviparous (egg-laying) cyprinodont fish (order Cyprinodontiformes, family Cyprinodontidae). The name killifish is derived from the Dutch word "kilde", meaning small creek, puddle. Most killies are small fish, one to two inches (2.5 to 5 cm).
