I'll be brief: I recently bought and read this book because I am building a new, elaborate terrarium. As a reference, this book is the best I've ever encountered. As a read-able book, it's also top notch. You would not think that moss could be interesting, but this book makes it so. Don't waste your money on books by Bartlett or Walls (anyone who reads herp books will know those guys know their stuff, but not like this!). If you're going to buy a terrarium book (discusses deserts, jungles, watery environs, etc. from beginner level to VERY advanced tricks and tactics), make this the one!!! You will NOT be disappointed.
