The criticism is directed in this case but the product manufacturer. The cave looks only half as good as the cover suggests. Everything simple unit Brown, although the article image comes in several colors. She is also much smaller than expected ... Unfortunately, the 15cm cave is barely 13.8 cm long. Even the outer carton is just over 14.5 cm long. Then can not be in there also, even if you subtract 2 times cardboard and bubble wrap. Regarding the inner edges, they are suitable due to the razor-sharp edges hardly for aquarium fish, without which you previously trimmed this halfway. This in turn is due to the brittle material to do with extreme caution. Due to the low price, but not worth the return. Since the Hersetller Trixie probably rounded up roughly! You will probably get a hidden place among the other roots.
I have ordered several items from Amazon for my aquarium, but disappointed I was really only this.
