multi species cage help....

[wonder_chunky]

i'll have an enclosure soon thats pretty large (not too sure on dimensions yet) and i want to put in a few different animals in there...i know that i'll put my werners chameleon in there because she is a nice small chameleon,and there will be a pond in it thats only a couple inches deep...so i was thinking maybe a frog or something, plus i need one more to go on the ground at the bottoms of the trees, i'm looking for more diurnal species. i'm breeding day geckos so maybe i could put one of those in?..i need to know what kind of animals can i put in there so that they can all live well and not kill eachother? (my cham is very very very very nice and she would harm a fly-heehee..unless it's food-_
