For anyone with an interest in raising "live food" for their exotic pets, this book has a huge wealth of information. The subtitle "63 black and white photographs" led me to believe it was little more than photos, but it actually contains detailed information on raising a wide range of organisms. It contains chapters covering feeder items including plankton, springtails, daphnia, worms, crickets, flies, waxworms, roaches, locusts, woodlice, rodents, and on and on!
The only fault I find with this book is that they should have done a better job with the translation and editing. It was originally written in German, and could have been greatly improved by some additional editing by a native English speaker familiar with the subject. In the section on Nematodes, the text jumps from vinegar eels to microworms without distinguishing between the two species, but I believe that this was an error, with some information perhaps being "lost in translation".
What's not to love about a book that features a pair of mating insects right on the cover?! This book is well worth having for anyone who raises live food.
