Initially I was not very enthusiastic for an artificial decor .... but this one is well done and quite natural. In a respectable size, offering plenty of hiding places and "caves" large enough, the fish love it! And it can be very interesting if you also hold crustaceans or fry. It fits perfectly in my aquarium 200 l. Holes on top allow not to trap air in the structure and can also be used to set certain plants such Anubia or Java moss. Reasonable price in my opinion given the material (resin), the size and quality of implementation. I do not regret at all that my investment has radically transformed the look of my tank and I will not hesitate to buy other decorations of the same brand.
