Will babby mollies eat new born guppies?
Definitely! Anything they can fit in their mouth, they will! Platys and guppies do it to, disgusting I know. That doesn’t mean to say that they 100% will, my sister has breed platys without them eating their babies and not having a separate tank for the babies. I would however advise trying to separate them as the babies are alive and I wouldn’t want them to be eaten if it were I!
