Here is my male (I think he's a male)

 
And the female!

Ok. I can confirm, males are quite aggressive towards fish smaller or the same size than they are.
The male I have already killed a female endler and kept nipping the tails of my neons and celestial pearl danios.
I don't recommend you keep them with anything else than bigger fish.

I guess as with all fish their personalities can differe greatly. My male doesn't even look funny at the neons and spotted blue eyes which are smaller.
The neons actually nip him, poor guy. Maybe I'm just lucky. I'm sorry yours is being a meanie.

Maybe he's just a dominant male.
I have given mine to a friend so she can take care of him in his own tank, he looks happy now and wont bother his new larger friends.
 
I am going to keep a few fry from the grow out tank to see how they do with other smaller fish. If I feel he won't bother them, I'll put them in my show tank.

Mine is in a tank with guppy fry and he won't touch them. I've never even seen it swim aggressively.

this is an old post, but in the video...what are the fish with the black and white tails?

The fish with black and white tail are Rummynose tetras.
