There is considerable debate regarding the true identity of this beautiful fish. Some authorities believe it to be the single representative of the genus Flexipenis, while others (probably a majority) believe it to be a Gambusia. Whatever its classification, with the characteristic black line running along its body, it is a delightful fish for the aquarium.
