I recieved a small tadpole (about the size of a pea) that just turned into a frog. However, it lost a foot while it was tadpole somehow. I'm guessing one of my fish bit it off. Nonetheless, its having a lot of trouble swimming in the water. It goes in circles because it only has one webbed foot. It seems to get really tired as a result of that. I'm not sure the little guy will survive or not because of this handicap. Will the foot grow back? This is my first frog so there's a lot I do not know.
