njmomie- If you are serious about trying to raise the fry, then you will absolutely have to remove the "community" from the community aquarium. The parents lack the size to fight off most "uninvited dinner guests." Also, snails and Corys will devour them given the chance. As far as parenting....most of the time, the male will drive the female away after spawning and will guard the eggs himself. They will alternate duties, usually when the male goes off to eat or chase away an intruder, but he will always return. It's also very common to have the parents eat the eggs after a day or two, or just after they hatch.
