Here's how should rename the book: the Bible aquarium shrimp. This guide is really complete, as its name suggests: breeding the presentation of shrimp species and aquarium crayfish as well as their natural habitat through a super table explaining which species can or can not live with other in an aquarium .... Superb book with a lot of great pictures :) I recommend this product if you decide to embark on an aquarium of freshwater shrimp !!!
