I would suggest--and it is only a suggestion, because the photo is not very clear and the fish are understandably stressed and thus not true colouration--that they may be Poecilia (Acanthophacelus) obscura. The orange is present, but no sharp black as on P. (A.) wingei. But it is also perhaps more likely that these are the guppy, P. reticulata.
Thanks for your time and answer, here some pics and video,
I'm kinda fascinating about small fishes, and P Obscura is kinda small, and yes it's not quite common here (LFS) that's why I wanted it (P. Obscura). Also that fish was from my grandma since she owned A farm and natural pond, she gave me as a present since I bought aquarium..^^
here's the vid and pics
