What zoo is this?

[Nile Hippo Expert]

Does anyone know what zoo this video of a Nile Hippo running from 2015 was recorded at? The video has become extremely popular in the past year. This is NOT A QUIZ! I just want to know which zoo this video was filmed at. I would also like to know the individual in the video if you also know that.
