Maybe you are getting ahead of yourself here. I would first be thinking about properly caring for them. Pairs are not that easy to obtain- sometimes it can take a few trades before you get a male this or a female that. Just focus on the care and when the time comes for froglets- trade with some friends.
I agree with you 100% that proper care should come first, i just had been wondering about this topic, so i asked. It never hurts to ask. I don't even have the frogs yet so it's sort of a "what if" question at this point. Thanks for the replys everyone
