good job making it to that stage
i tend to let both parents take care of the fry unless they start fighting or 1 decides to eat the fry. I am not aware of a partition that they will not be able to swim around, so the freeswimmers will ignore the partition and end up as a quick meal. if you want to breed them, dedicated a breeding tank to them.
with the right net/trapping device, i guess you could move them...although the parents may not react well to the sudden switch to a totally new environment...especially with the fry.
