swordtails
Freshwater tank pets
Swordtails are small freshwater fish native to Central America, popular in home aquariums.
Males have a distinctive elongated lower tail fin that extends like a blade, giving the fish its name.
They're livebearers—giving birth to free-swimming young rather than laying eggs—and are prized for their bright colors and ease of care: The swordtails in our tank just had babies.
