The swordtail comes in a large variety of colors. Like the Mollie, Swordtails require a large tank for free-swimming in order to keep their growth from being stunted. Guppies and Mollies can be crossbred. It is also said that Guppies and Swordtails have been crossed to create the swordlike tail of the Swordtail. However, because there is not concrete evidence of this cross, scientists find it more logical to assume a chance development in the tail.
