Hey, I went out last week and caught some tadpoles to raise them up, and take pics of them developing into frogs. They are about 2 1/2 inches long. Someone told me they are bullfrog tadpoles, but I've seen bullfrog tads much larger than these without legs, and these guys already have back legs (most of them). I went online and searched for Northern Leopard frogs and saw a pic of a tad that was similar but I am not sure....I plan on keeping two of the 19 when they morph into frogs, but I want to make sure of what I"m gonna get before I start setting up a tank for these guys. Here is a pic of one of the tads. I can take more if needed.
