mollies are a breed of fish, so there is a variety of mollies including the black lyretail molly, the ballon molly and the dalmation molly. But all mollies have pointed noses and their underbelly curves down but their back is more straight. Male mollies are bigger and thinner compared to female mollies. If you look near its stomach it will have longer fins compared to female.

Black Mollies aka speed or amphetamine
i would suggest putting a separator between them.
i have a guppy and two black mollies in the same tank,and they get along perfectly fine so far.but sometimes,you get the occasional aggressive molly and it might attack your guppy. you should also ask your local pet store to see which fish can get along and which can't.
