Will my black molly baby eat my baby mystery snails?

i dont think, hmm you do have a predicament here, I wish I could help, I would get my money back first off you didnt pay for snails you paid for plants lol and hmm i would think just clear the plants of remaining snails and then take the baby out and add about a good cap and a half of bleach and then start the tank from the ground up again, sounds mean but works, no more snails though or you can keep a couple you may want and then kill the others or just kill them all wow I sound bad, I have fish, my fish would be weirded out if they heard this lol just thought I would add a little humor and help you out so hope this works
