I just wanted to post in response to the bit there about the leaf litter, as I have only had my Sisa for a short time but long enough to have learned that it's absolutely SPOT ON! I have a seariously thick layer of magnolia and oak leaf litter, along with lots of wood, liana, coco huts, almond pods etc, giving the frogs a LOT of hiding places, yet I see them constantly. They are always out and about, climbing the glass, balancing on the edges of magnolia leaves, climbing liana, perching on brom leaves etc. They actually act bolder than my azureas or leucs do. So yes, the more hiding places and leaf litter you give them, the bolder they will be as my litte guys (they're only youngsters) couldn't get any bolder if they tried.the Saposoa bassleri are rather bold, Sisa can have a tendency to be rather shy. This behavior may abate when breeding behavior is witnessed, and with the introduction of dense leaf litter and broad leafed foliage.
Just to add, their viv is in my living room, with 4 kids, dogs, a cat, people walking past all day long. They will hang off the front glass and actually watch people stood right up close.
