Catemaco is not just famous for its brujos and disappearing fauna and flora. Thousands of aquarium hobbyists keep a piece of Catemaco in their tanks. Best know are the Catemaco Molly and the Catemaco Platy. The video is of a rare Catemaco species, only discovered/described in 2003 Xiphophorus kallmani, a livebearing swordtail.
