I had set up a little net, but it was not sturdy enough for the bigger crabs, so I had to redo everything again. lol. I changed up the second level and made two ways to climb up. I made the net more stable, and then used a plastic tube and weaved sponges on it to make a sponge climbing pole. I added a larger container and created a salt water lagoon, then changed the container for the fresh water and used a plastic palm and sponge to make an "island". They all seem to enjoy it and nobody has fallen since I redid everything. Check out the gallery for the pics. Leave comments and suggestions PLEASE!
