I just got a copy of Back to Nature Guide to Nano Aquaria form Rachel for $30 shipped (beats Amazon). Besides general information on nano tank setups, most of the book is about shrimp, snail, plant, and fish species that are appropriate for nano tanks. I saw some fish species that I never heard of before. The only part I found not always true was the authors' evaluation of how difficult some of the species are.
All in all, it's a great book that I wholeheartedly recommend.
Ditto on the book! Checked it out when I was up visiting ms. jinxd and had to buy it. Great book! Lots of pictures, and neat stuff. Highly recommended.
I am getting about a dozen more in case any of you want some If you get a few people together, I can match the group buy price. Bought individually they are $27 each with $2 for media mail shipping
