Another volume compiled by our Expert Dr. Lothar Seegers. Many of the 550 color photos have been taken by himself. The groups of panchaxes, Aplocheilus, Epiplatys, Nothobranchius, Aphanius and others are introduced in this sequel, again with all varieties, localities and exact scientific names. Their colors and size (most of them reach only 3 to 8 cm) make them the ideal aquarium inhabitants. The first volume already triggered off a rising interest in killis. All AQUALOG -reference books introduce each fish (incl. breeding forms etc.)with at least one color photo and a short description. The ingenious code number system labels every known or newly discovered fish with an individual code number. This number re mains, despite any scientific renaming. Moreover, it enables you to communicate internationally about any fish without the danger of confusion regarding local names!
