If a larger fish can fit a smaller fish in their mouth, the possibility that they will is always going to be there. . . I've had really good luck with Mollies. Even my adult Mollies didn't eat their newborn babies - but others have had the exact opposite experience! Best to be safe and separate the two groups if you want to ensure that they all survive to adulthood. It won't take long for you to be overrun with Mollies at this rate, lol!
