I'm in the process of setting up my very first crabitat (no crabs living here yet... am adopting two small ones from a relative in a few weeks). It's a 20g long. So far, I've got some water pools, a DIY hut to hide in with a dish on top (I glued them together so it's all one piece... the top part will probably will be the shell shop), and a couple of boardwalks for a second level. I need to add a moss pit somewhere, and would like to add some climbing structures, but am not sure how I want to lay it all out yet. What do y'all think? I was leaning toward putting a moss pit either over the pools or in the corner in front of the hiding spot/shell shop. What else am I missing?
I'm having trouble taking good pictures, but you can get the idea. The substrate's a bit higher than it looks like here (it's 5-6" depending on the side of the tank).
ETA: Hopefully the pictures work now!
