i had a pair of german blue rams myself, they bred every month like clock work it was pretty cool. i didnt separate them from the eggs though, it was interesting to watch the parents move the eggs to a more suitable spot with their mouth, they just pick em up and spit them out. after they were born theyd herd them together in the same fashion you dont really have to worry about them eating the babies in my experience i noticed that they spent more time protecting the eggs and babies than hurting them, though after the babies a a few days old id put a divider in the tank so they can grow a bit i found it very easy to breed them
