Raided the Amazon bookstore for a number including the Nano Reef Handbook amongst others. Best one by far though is an underwater masterpiece of Photography - Roger Steene's - Oceanic Wilderness. Having been lucky enough to dive in Indonesia & Malaysia, some of the photographs provoke some great memories and have been an inspiration for the Biocube 14 project - much more than any of the standard Marine Aquatic Tank Guides.

Not an Aquariasts book but just trust me and order it. You won't be disappointed !
