Anyways, I agree though it's not really wrong for fish to eat each other. Generally not encouraged but sometimes it has it's purpose.
That's why we're encouraged to try and simulate the most "natural" environment we can when keeping aquariums. The OP didn't specify how they'd like to scape their tank, or if it were to be a single species or multiple species tank. Common sense plays a role in the decision making. If you'd like to get a fish, and let it have babies, and hope those babies survive, you obviously would make the necessary changes so that those fish survive, i.e. plants and hiding places, etc, while still remembering the stocking rule, fish will eat whatever smaller size fish can fit in their mouth. If they clearly stated they wanted to own a livebearer and not have the fry to deal with, I'm baffled as to why people would advise a tank full of female mollies.
