Yes they are the same species . The only difference it the colour. Just like a black person having children with a white person.
Mollies actually give birth to live young, they are one of the few tropical fish species who do this.
no it will not mate in any couse
Not live ones!
Yes, black mollies can be fully acclimated to saltwater.
Mollies and black bettas.
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.
about 6 months
They may be too crowded. I have heard that mollies need 2-3 gallons per fish. My daughter's male dalmatian Mollie keeps nipping at the female and has killed 2 so far.
Black Mollies aka speed or amphetamine
i would suggest putting a separator between them.
