Another premiere by AQUALOG: the first reference book to show not only the well-known guppys, mollys, swordtails, platys etc., but also all others, in over 2,000 color photographs. All wild and breeding forms and color variants as well as halfbeaks. Your AQUALOG -reference book always stays up-to-date! All newly discovered or bred species are regularly published as supplements or so-called "stickups" in our AQUALOG News. These stickers can be attached to the empty pages at the end of your book.
