Yeah - I actually have that exact same setup, almost. I bought some plastic craft sheets and made a table out of them with hemp to hold it together and a tube that I stand on its end. The other sheets out of the pack are to help the crabs have traction on the floor. I've taken mine out around 5 or 6 in the afternoon for a week now, and the food bowl gets more attention and the three crabs that are out have been out at that same time every day. One even will climb onto the lid to get attention and, when I pick him up to set him back in the tank, doesn't want to climb off of me! It's awesome; he's so tiny, it feels like he's hugging my fingers. Granted, most of what my crabs do is try to run up the smooth sides (it's like a crab treadmill!) but I put them up on the ornaments every so often. One of them has figured out that he can climb up on stuff, and does it more than the others. Before I take the crabs back to the cage (after 30-60 minutes of exercise) I put them in the tube and then take them back once they've climbed out and back down to the floor level. The crabs are getting much more comfortable with being handled, too. I love it!
