UPDATE!!
two of the tadpoles now have four legs and are resorbing their tails! A couple look like they will soon grow their front legs too. this is so exciting!(: The tadpole I mentioned earlier that grew all the legs has now almost completely resorbed its tail! This morning I awoke to find the 'oldest' tad on the wall of his tank! And yeah they have small pads for feet. Oh! and is it safe to use a terra cotta pot holder as the 'shallow water dish'? thanks guys!!!
