Can you post a picture of your full tank setup? I see the pvc and clear bins and I'd love to see the whole setup to get some new ideas for our crabitat. Thanks!
This is the most recent picture of the setup I have. I then replaced the stump you see behind the cholla on the left with a piece of palm…bark? boot? that I got from the Hermit Crab Addiction Store. They don’t have any of the palm anymore, but they have black oak bark, and all kinds of cholla.
After the palm piece, I then got a piece of upright cholla to replace it as a way to access the middle level on the left.
Have fun with your tank! I always enjoy a good tank redesign. Keep in mind that any wood items you have in there will be eaten by your crabs, and the damp part where they touch your substrate could get moldy, so check them periodically.
