Saltwater Fish Nutrition: Suggested Herbivore, Omnivore, and Carnivore Diets

Written by PetCoach Editorial

When choosing a food, the first thing you need to know is what type of diet is natural to your fish. All fish fit into one of three categories:

  • Herbivore a plant eater
  • Carnivore a meat eater
  • Omnivore a consumer of both plants and meaty foods (the vast majority of aquarium fish fit into this category)

Many of the staple diets do a very good job of providing a broad range of essential nutrients required for good health. Variety in the diet is important to good nutrition and the well-being of your fish. Offering supplementary foods in addition to the 'staple' diet assures better nutrition, and enriches the diet of your fish with more tastes and textures.

While there are many high-quality foods available, we have had particularly good results with those foods and brands listed below. The chart indicates whether that fish is classified as a herbivore (H), carnivore (C) or omnivore (O), and offers good choices for both the staple diet and supplementary diet. Some fish, such as Blennies, are listed as belonging to more than one category, depending on the particular variety. Make sure to research the dietary needs of the specific variety of fish you own.
