There are around 1,270 species of killifish and almost any warm water climate  in the world has a species of killifish somewhere, or fossil record that a species of killifish once existed there. The species vary in coloration and finnage, and though they are closely related to live-bearing tooth carps, they are egg-laying fish—but in a way unlike any other fish on the planet.

These killifish species are often called annual fish because they may live one season only. These species have bright vibrant colors and beautiful finnage but a very short life span. Though beautiful for a brief and splendid period, they quickly begin to fade, wither, and die. It is not the fault of the hobbyist when this happens; even under perfect conditions, it is the nature of things. The life span of this fish is short, and the fact that a dry season never comes in the aquarium does not change that.
