I know a lot of people do it, but I personally have really disliked my experience with divided tanks, too. Critter keepers are AWESOME - great deal on that one! Hope you get all sorted out soon, and can start building that big ol' tank :) 8 frogs sounds fun!!! I'm planning to upgrade my 2 to a 10g, and was thinking about adding a few more to the bunch when I do that - OF COURSE! Frogs are addictive! They're just so SWEET! Seeing the two together has me wondering how much more fun . . . well . . . MORE would be! I'm thinking I might round them out to 3, and after a while I *might* give them a fishy roommate. But we'll have to see about that one, because feeding them (for me) in community was a real pain. Of course, those were MOLLIES I was fighting with. There are other critters that might be easier!
