Thanks for the great input! We got the frogs finally about three weeks ago, and they're quite amusing to watch.

The tank is probably about 3/4 water (I am honestly just guessing). I got some great aquarium plants, but they've since been destroyed by the frogs hopping on them and such. I'll have to figure something else out.

I have found that they will eat pretty much anything we put in there. They're not as big on the fish, but that might be because they're underwater the whole time? They sure love crawfish, though! It's really nice that there's a bait shop within walking distance from my house. I can get them worms, fish and crawfish all at once! And what must they think when I tell them it's for pig frogs? o.O

I will upload some pictures soon. I have a silly one of her sitting on the water filter--because she doesn't know that she's too big to do so. Heh.
