On top of this article looked very funny, so artificial. When he dan first time in the water was, he made a great impression. It is very passent for smaller aquariums (20-30L.) As it is not a 2m thing is so. I bought it mainly as a cave for my cancer, it has been well established. It looks very nice and fits well visually with other decorative items on. There are 2 "inputs" of a more like a window and the other for larger animals (cancer). There is also a kind of stone plateau. In the cancer can climb.
