How long does it take if a bullfrog tadpole already has back legs?
A week or two depending on how long ago it hatched.
It always depends on the species. A tree frog took about 5 weeks
(a little over a month), and a bullfrog tadpole took 2 years!
Usually, tree frogs and smaller frogs take less time while massive
frogs such as bullfrogs, pacman frogs, and others take years.
