Last year i got my bullfrog tads from a local pet store. I was also in the process of making a pond for them. well i had to keep them in a tank over the winter because my pond wasn’t ready. they’ve been in the pond for about 2 months now and i saw one today and he is starting to look different. he still has a full tail, but his head looks more frog shaped and his back buds look better. i really couldn’t see if the were feet yet because he was kinda deep. how long do you think before i have a new little frog?
