Hello there just to share Freshwater Stingrays from Amazon. Inside this video got two type of Rays they are categories under P13 - Potamotrygon Leopoldi or by short Polka-Dot Ray and other one small in size color of black and white very strong is Black Diamond Ray. They can be found at Xingu and Fresco Rivers Basin , Amazon Brazil. I love this Rays until the extend i keep for my fish hobby and they usually feed on live feeder fish like goldfish , earthworm,bloodworm, ghost shrimps , tamban fish meat and squid. All my Leopoldi Rays are Captive Breed . ENJOY THE VIDEO !!!
