I have only had one dessicated dageti, they live in a 300 x 150 x 150mm tank with no lid but there is a large crypt in the tank, which they like hiding in. Will post a pic when I have done the photo comp, Gannet is getting impatient!
We used to see smaller brown ones, and katydids, which look like leaves.
Some id info here, but not much data.
