Can I keep these two frogs together?

I got them both as tadpoles and they were both supposed to be Leopard frogs. I believe the first IS a leopard frog but I'm afraid the second is a bull frog. Here is a picture of the tank I have them in. It's a 20 gallon. Right now the leopard frog is slightly larger than the other. (I got him first.) The leopard frog hangs out and the "dry" half of the tank and hides behind the leaves all day. The other frog stays in the water and doesn't hide, or seem to care if you walk around the tank. I'm afraid if it is a bull frog it will get large and eventually eat the leopard frog ..... is this a correct assumption?

ANY comments or suggestions would be appreciated. Should I keep them together or do I need to separate them?

You are correct. If your bullfrog outgrows your other frog it will eat it. Bullfrogs will eat anything they can fit in their mouths.

Am I correct in guessing that second frog IS a bullfrog and is going to get pretty large? What kind of a habitat would a bullfrog need?

Yes, your other frog appears to be a bullfrog. A bullfrog would be fine in a similar setup, but maybe less land more water. They get big, so you'd need a lot of space. The 106qt sterilite tubs would be a good candidate. You could use two, one inverted on top of the other, to make a large & tall enclosure. Just make sure you provide ventilation via holes w/ screen melted or hot glued in.
