Some Killifish Definitions

So you already know what a killifish is or you wouldn't be here. However, I was interested in the actual definition of what makes a killifish a killifish and how they are perceived as such in the world.

Some definitions that came up when I googled killifish definition:

• small mostly marine warm-water carp-like schooling fishes; used as bait or aquarium fishes or in mosquito control (bait??!!)

• A killifish is any of various tiny, oviparous (egg-laying) cyprinodontiform fish

• Any of a number of tiny fish in the Cyprinodontiformes order of ray-finned fish

• Egg laying toothcarps. (Compare Livebearers). There are two types of Killifish, the Annuals and the non-Annuals

• A very beautiful group of fish, which can be quite hard to find.

• These are fish with a low life-span, often only for a year. Sods law, they are also some of the prettiest.
