I recently purchased some black and one dalmatian molly females for my two silver males in hopes of calming them down. My question is, can these all breed, seeing how they are different types of mollies? The silver males seem to be interested in the black mollies, but show no interest in the dalmatian. She has tried to get their attention, but they just act as if she is of another species. Is this common? And what will come of a cross between a silver and a black molly? A dalmatian? Or some silver, some black? Any help/answers would be much appreciated, as I'm more than a bit confused.
