I'm no export in these kind of frogs, but at least Theloderma corticale are semi-aquatic/semi-arboreal. They're basically tree frogs (which means a lot of climbing space) that like to swim. I don't know if they other are as well, but they're not, they're probably have quite different tank-requirement.
One more thing to consider: It's almost impossible to get a female, at least here in Sweden. They didn't even have females at Hamm.
