BEHAVIOR AND REPRODUCTION
Males of some species of killifishes and live-bearers are aggressively territorial, defending their breeding sites against other males. The fishes that live in temporary habitats such as ditches lay eggs on the bottom and die when the water evaporates. The eggs go into a resting state and hatch in the next rainy season. Killifishes that live in permanent waters spawn, or release eggs, in plants. The eggs stick to the plants. When the young hatch, they are fully capable of swimming and feeding.
