The small family of blue eyes includes two of the most popular aquarium fish in recent years: the fork-tailed blue eye (rainbow fish) and the spotted blue eye. Since blue eyes do not grow too large, they are also suitable for the new trend of nano-aquaristics. Hans Herbert Boeck knows these "butterflies in the aquarium" like no one else and not only provides an overview of the diversity of blue eyes but also vividly describes the recipe for their care and breeding. Each book in this series introduces the most popular freshwater aquarium inhabitants, species by species. Each volume offers easily understandable information about a specific group of aquarium pets, explains their biology, and describes their care. Experts with many years of experience provide detailed, practical care instructions, and you will find all the information you need for successful keeping. All of this is presented in full color, generously illustrated, and attractively designed - species by species.
