Foam questions, part 2 ... w/Caatinga pics

[emandkel]

One week after using foam, I see these advantages:

--I can see them easily
--I can easily seen poop and how often they do so (or lack thereof)
--No danger of eating any substrate when feeding

The three (pacman) frogs I have on foam are eating well and seem to be doing fine.

The main disadvantages are daily cleaning and the frog's lack of a place to burrow.

My setup, currently in medium Kritter Keepers:
--3 layers of 1/4" foam
--about 1/4" of water in bottom (not enough for the frog to be sitting in water)
--a water bowl (bigger soon, as they can barely fit in these now)

I will be adding some sort of a hideout as well. I mist the frogs directly lightly once or twice a day, which they don't seem to mind.

--My main question is, does the water level need to be up to the top of the foam, or is it ok as it is with the water bowl?
--I have still been changing all water on a daily basis. But if the water under the foam isn't touching the frog, does it still need to be changed daily?

Finally, some Caatinga pics. I am pretty sure I heard this one croak last night or the night before (he only croaked about 4 times, though). The last pic is taken from outside of the Kritter Keeper thus the clouded look. Does his throat look like it's a male?
