Funny you should ask ...
They've been in separate boxes, terrestrial with a small water dish, 10-15C & reduced illumination since 01/11/05. Tomorrow they both go back into a 50:50 tank at 15-20C with a 12:12 light cycle. I expect they will remain terrestrial. They don't know it yet, but after one week, the water level is going to rise 5mm per day until the whole tank is flooded with just a small corkbark island.
Then we'll see ...
