Video of a captive bred Xiphophorus xiphidium population. This wild platy species is to be found in the Rio Santa Engracias at Tamaulipas in Mexico. Males of this wild platy species can (so, not all) develop a very short translucent sword. A female would prefer a male with a short sword instead of a male without a sword. And if a male shows strong vertical bars on the chest, is also something that females see as being attractive.
