Another wild swordtail species...
My nezzies...
Mountain swordtail (Xiphophorus nezahualcoyotl)...
The males of this species will develop a short translucent sword. Back in time, it was thought that this species was a montezumae swordtail species. But it's a complete different swordtail species.

nice looking fish are used to keep them back in the early 1990s

I love that fish and really regret losing mine.
