Beings on the second book in french shrimp grading is easy to do. This is the best of 2. It is well detailed and provides a good start but not beyond. It lacks for example in Table 6 pages with all species: a page number to find them, the PH value and temperature. to choose is better. So I handmade. It is amusing to note that some species the table are not described. AH AH. It also lacks information on the ground. The desciption is very good on the different types, but curiously silent on the right to use whether you need a rather light soil and fine, heavy and big! It is said that a particle size of 2mm mini is better for the bacteria but for shrimp? Ditto on decontamination after purchase. When I buy my fish they immediately leave for 40s bin, are treated and preventive manner observed and, finally, hopefully introduced into farms or my community bins. No desciption of GH, either specific KH ... pending more comprehensive it is the best *****
