This handsome volume is designed exclusively for divers and aquarium hobbyists. Covering all of the world's species - 83 angelfishes and 121 butterflyfishes, it is the first comprehensive guide to these popular families. Few other fishes are so intimately related to the coral environment, and none exhibit such a remarkable array of dazzling colour patterns. Every species is illustrated in full colour, with extra photographs provided for the very different juvenile and sex related forms of some angelfishes. This valuable reference contains a wealth of information pertaining to behaviour, life history, distribution and aquarium maintenance of these remarkable fishes.
