Guppy Breeding Behavior

Breeding behavior in guppies is quite unusual and fascinating. The male guppy will actively seek out a female for mating, often swimming around her for an extended period.

When successful, the male will nip the female’s tail to begin mating and release sperm into her water.

After spawning, both sexes usually swim away from each other; however, male guppies may attempt multiple mattings throughout their lifetime if given opportunities.
