Book 1 of Nature Aquariums is the book to get from this 3 book series. All the books are pretty much the same, with limited how to info but an abundance of pictures to look at to become inspired. The difference lies in the fact that this book offers the best looking aquascapes.
I would purchase this book, if you are looking for something in your hands to look at. But otherwise, I would just look at pictures from other people on the internet, or aquascaping contests for inspiration and a more how to information.
Thick paper, hard cover, and well designed with beautiful pictures
No text to describe aquascapes and how to instructions
