Guppies are "common" livebearers. By this the males have gonopodiums. The Gonopodium is a specilizied anal fin that has a sperm tube. The males have the ability to swing this fin either to the right or left almost one hundred and eighty degrees so they can deposit sperm in the female. You can tell the difference below.
