" In summer 2013 a recently discovered location for Girardinichthys viviparus was published. The specimens were found in the town of Mexico City, just a stone's throw away from the gate of the international airport. The water body in which those fish were found is located in Alameda Oriente Park and is used for recreational purposes. The examined specimens showed a significantly larger body shape compared to hitherto known fish of this species, possibly because of the abundance of food and low predation pressure. The sex-ratio was unbalanced with a value of 1:2.4 "
