I have some large rocks in there for land right now. I used to have 1/2 land 1/2 water and I would CONSTANTLY have crickets drowning... then I went to mostly land and just a pool and they were STILL finding their way into the water and drowning.
They are such a pain. I enjoy my new setup the best. There are lots of places out of the water for the frogs to sit. The reason I said there's not enough for the crickets is because it doesn't seem to matter how much they have, they always end up in the water.
Where can I get some of that corkbark? I have also seen large silk/plastic lilly pads that would look nice. I might invest in one of those also.
Here's a pic of my current setup.
