It's wise to remove the babies to a nursery tank before the parents start breeding again. They aren't cannibalistic, but are very territorial, and will intimidate the little ones after a month or two. No dart frog is cannibalistic, but some species of the tadpoles are, and will kill each other if raised together. These are usually the egg eaters such as thumb nails. D. imitator tads for instance, are decidedly cannibalistic, so must be raised in separate compartments, whether by the parents or you. After they morph out, it is perfectly safe to leave them with the rest of the gang. Since pumilios are obligate egg feeders, they will place the tads appropriately, usually only one to a brome axil or whatever container you provide, and probably won't bother the baby froglets for the first few weeks, at least. I have left the froglets together in the same nursery tank for up to four months without problems. Then you can separate them and see if you can sex them and hopefully get a new breeding pair going.
Congradulations, by the way. The true Blue Jeans morph is hard to find at this time, so you're really fortunate to have a breeding pair.
