I bought this tadpole from a pet store, hes olive green like solid color, very very light yellow or maybe even dull white on belly, hes getting very large has two small hind legs now, his tail is partially transparent, im thinking either a bull frog which i oppose because hey take nearly 2-3 years to transform, and this one ive had for 2 months i cant believe a pet store would get a 3 year old tadpole.. my second guess is a toad. thanks.
