In my case, the piece of root has served its purpose. When I describe it, I would say: it is long, a piece of wood, holes un has a hiding place.
I just wanted to have something that my mud crabs can easily climb on the land part and I can fit well with moss, but the piece of root has very well done (I am very satisfied). It provides the crabs also a hiding place and there will also be times of what verspeisst.
So you should not have too high expectations, but perhaps you should simply times surprise!
