Never Give Up: Little Fish Manages To Swim Up Perfectly Vertical Stream

Because never give up *insert cartoon of frog choking the stork that’s eating it* this is a video of a small fish managing to swim straight up in a small waterfall streaming from a pipe, while a couple of its friends also appear to defy the laws of physics. How did that one on the right just freeze in midair like that at the very beginning? Whatever the case, I think we can all agree that when Nemo’s dad sets his mind to something, he does it.
