Once they're established they will sort of breed like dart frogs, which is to say, on and off throughout the year. You don't have to pull the tadpoles, just let them fend for themselves in the parent tank. I wouldn't worry too much about it though. The sex ratios in captive populations are really skewed right now, so you'd probably need a group to get any breeding. Either way, I wouldn't worry too much. But no, they don't need any special setup or cycling to encourage breeding.
