I have a 6 gallon nano tank. The parts were smaller than expected and not in the shape I expected. I had to trim most of them because there were a lot of tiny/thin knots on one side. The third piece was awkwardly shaped and didn't look good no matter how I inserted it. I only have 2 so far and they look decent. They were very inexpensive so I think they were worth it to make the aquarium look more natural. Don't forget to cook them!
