Anyways. You know that coconut fiber lining for hanging plant baskets that they sell at most gardening/home improvement stores? It's fairly cheap and safe for crabs (make sure to ask for the organic, pesticide free kind). Just cut a piece the size of the climbing wall you want to make and... this is the part I haven't quite figured out yet: how to attach the matting to the wall of the tank. In my tank, the lid is heavy enough that I can use it to weigh down the top of the matting and prevent it from falling. However, this is impractical for anyone with a light lid/ large crabs.
I would love suggestions on how to improve this toy.
