And here is The Crabitat.
A 55 gallon with plexiglass sealed in for permanent filtered pools. I have burlap glued to the back and to the pools, which they love to climb. The floating moss pits are also glued to the back bc suction cups hate me.
Not seen is a 4ft heat mat that I put behind the tank for pics, but I usually keep it on top of the tank to also keep in humidity.
Still a bit of a work in progress, but right now it suits all their needs.
