swordtail

Pointed-fin livebearer

A swordtail is a small freshwater fish native to Central America, popular in home aquariums.

Males have a distinctive elongated lower tail fin that extends like a blade—the "sword" that gives the species its name.

Swordtails are livebearers, giving birth to free-swimming young rather than laying eggs.

They come in many color varieties through selective breeding.
