I've got a couple questions about these frogs which I need answers too. The first concerns caging requirements. I have room on my frog rack for another 18 inch tall exo-terra. Is an 12x12x18 enough to house 3 of these frogs? If not, would an 18x18x18 work? I would really like at least 3 if I decide to go with Barkers. My next question concerns the noise these guys put out. I have a group of Gray tree frogs and I could probably deal with frogs a little louder which call even up to 3-4 times more frequently, but beyond that I've got my own sanity plus other's considerations to take in account. So how bad is the noise? Any information will be greatly appreciated. Thanks, Mitch.
