Can anyone please tell me my fish's genders? (by watching a video of my fish) Thanks! =D

I have 6 fish. 1 blue, 1 pink, 1 yellow, and 3 black skirt fish. If you can, could you please answer me each of them's gender? (by colours or size... to let me know which one is what gender!) =D Here's the video link to my fish!
