I think they all are toads at least. I live on Long Island, NY and late August we had heavy rain causing flooding in a parking lot at a large park and eggs were laid in a temporary pool in the middle of the parkinglot! Right after next week we had bad heat and the pool was drying up quickly, I took a few tadpoles home, the rest at the park all perished the pool dried up completely. Not many species breed at this time of year, I thought eastern spadefoot or grey tree frog, or american or fowlers toad. Anyway, most are nearing adulthood and I have one toadlet, trouble is its in the 50's at night here and these guys belong back in the wild I dont want to keep them, I want to let them go as soon as the toadlets start to hunt which this one is at. But its wont eat the fruit flies its tries but has a hard time, in the wild there are smaller prey like springtails at least. I need to know species of them and when its best to release them. Here is thread with photos of them growing. What frog/toad tadpoles could they be?
