Nutrition, Anatomy, Health, and Diseases

The nutritional needs of each individual marine species vary widely; each has its own special food preferences and requirements. While it may nearly be impossible to reproduce the exact diet that the marine life in your aquarium would eat in the wild, there are many types of foods and feeding methods available to the aquarist. Learn some nutrition basics as well as more detailed recommendations for specific species.

The anatomy and physiology of marine species has many unique aspects, with organs and systems not found in land animals. But, like other animals, marine species can have bacterial, viral, and fungal infections, as well as parasites. Learn about the normal body functions of marine fish, invertebrates, and coral, as well as the diseases that can affect them.
