Volume 1 of this book series provides the technical and chemical fundamentals for the successful maintenance of a coral reef aquarium. Building on this, Volume 2 delves deeply into aquarium types - from community and cave aquariums to biotope tanks, the possibilities for decorating a reef aquarium, particularly with live rock, the feeding of fish and invertebrates, as well as the most common parasites and diseases. A comprehensive chapter is dedicated to the breeding of fish and corals - a topic that is becoming increasingly important not only due to existing species protection regulations. Additionally, suitable aquarium inhabitants and their acclimatization are thoroughly presented, and there is a discussion on algae, including the management of algae outbreaks.
