what is this guy?

ditto on american bullfrog tadpole. american bullfrog tads have pinpoint black spots while green frog tads have somewhat blotchy, larger black coloration that is not uniform small black dots. american bullfrogs tend also to have less coloration on the bottom half of the tail. i should comment that the body shape (seems like it has a flatter head) is actually more typical of a greenfrog tadpole.

Part of the flatness was the container he was in making him look a bit different, pic when I got him home

Well, his/her coloration does appear strange, but that might just be the photo/camera. Nonetheless, I'm still voting on either an American Bullfrog or Green Frog. Keep us updated on him/her.
