Yes, please focus on the basic care first, as Jennifer has said.
When the adults are happy, they will eventually lay eggs. But keeping the larvae in the adult tank usually 99.9999% of the time wont grow up. Unless you have a large tank, like a pond, with lot of microorganisms for the larvae to feed on.
Usualy when raising the larvae to junvenile stage take a lot of efforts. I have 50 CO at home and when they were young, they took me two hours everyday to feed them. So please put these into consideration.
