Hi, I'm think of getting one of there frogs too, they look very interesting, more like a stomach with eyes than a frog...
I'm a newbie too, here's my tank setup for my toad, try setting your up like this too, I'm sure I'd work much better, and when I get a Pacman, I am going to set it's tank up the same way as my toads tank.
I have roughly 6 inches of organic soil on the bottom, 5 live plants, I don't believe in fake plants, a few sticks and 1 log, a little hill with the toads water dish on top, and the lower part of the hill is hollowed out to allow the toad to burrow, and quite a bit of moss which holds moisture very well, and gives the toad a place to sit/burrow. I don't know that much about Pacs, but I think this tank set up would work well for them too.
