White's plus Tribolonotus?

[aquamentus11]

I just ordered a baby, male Tribolonotus gracilis and am thinking of ways to set up the 23" repti-racks cube I had ordered for an ATB. I am no longer going with the snake (obviously), but I still have all this extra head room that I doubt the skink is ever going to use. I was thinking of putting a tree frog up there, but wanted to check with more-informed owners whether or not this would work well.

Both species eat the same things, are both nocturnal and require similar temps and humidity. I have a few of those magnetic rock ledges that I was planning to put up high for the frog plus live plants, branches yadda yadda. I would get similarly sized animals to start off, but how quickly do the frogs grow? I know they take pinkies once in awhile as adults and don't want my skink to go down that road. The White's tree frogs look really fun though and I'd love to take care of both species, though it would also be cool to have a diurnal frog with the nocturnal skink. Does anyone have any suggestions as far as diurnal spp. with similar requirements?

Thanks. I'm new, but if this works out, I'll be on here much more often!
