This video is called Fathead minnows feeding.
By Frank Spikmans (RAVON) and Sjoerd van Veen in the Netherlands:
In a pond in Neede (Gelderland province), a reproducing population of fathead minnows has been discovered. This species is native to North America. Probably the pond fish trade brought the fathead minnow from the Americas to Europe. The species has already been observed in Belgium, and there are reports from France of successful reproduction in the wild.
