HCA: Hermit Crab Association

So I recently purchased a 40 gallon breeder tank for my 6 hermit crabs.
I am waiting for my ultratherm to come in before I put them in it,

Does anybody have any photos of 40G setups that they might be able to share?
I am a total noob when it comes to crabs, and I want to make sure that my tank is set up efficiently for them.

Another question, many people have suggested adding a 2nd level, should I be worried about my crabs slipping and falling? I would hate for them to become injured, they seem so fragile!

I don't have a 40 gallon so no pics/advice there, but as far as a 2nd level nope, you don't have to worry about them falling. If you have the right amount of a substrate, the distance they'll fall won't be more than 12" and they should be fine. My guys have fallen a couple times in their tank when climbing, and they just scuttle off and try again. I'm sure in the wild they climb much higher and fall farther. The sand is a good cushion, and their shells help protect them as well.

So, I'm not plagerizing, this is not my original idea, I shamelessly borrowed it from another member. If you go to the hardware store and purchase "corner protectors" and drill holes in one side, you can then silicon them to the upper lip of the tank, or at any heighth. This gives you a stable way of creating second or even third levels with zip ties.

You can look at my post.

These pictures aren't great but this is the 40 gallon I did for my mom. No second level and I sloped the sub down to the water. There were 2 medium/large crabs, two smalls and one tiny in the tank. There were two live bromeliads, a bridge/hide, a cave hide, cholla, and aquarium plants. The FW and ws pools were really big reptile dishes with beaches.
