I don't know what they're called, but I roughly know what they look like full grown. I got them from a pond near Seattle, Washington, and saw a couple full grown frogs there, most likely the same type. I don't really know how to adequately describe it, do you know of any websites that I could go to to help identify it? It was a pretty average frog in my opinion, not very colorful, dark shades with some freckles. Maybe about an inch or two long. When I found them, the pond was practically covered with all the tadpoles, and there was a lot of green algae. Thats all I can remember right now. The sick tadpole isn't doing so great though, it's barely moving anymore.
