You're right he also looks a like a pig frog. Could you rephrase about the toes, I'm not sure I quite understand. pig frogs' 4th toe do not extend past the webbing, or do? Also thank you for all the other replies!
[Edit]
Never mind, I understand now. So I have heard they are almost fully aquatic, so what kind of setup would be good for him, if he does end up being a pig frog? also do they eat insects like crickets?
