Find the Right Food for Your Fish

Whether you keep a freshwater aquarium or a marine reef system, proper nutrition starts with understanding the natural feeding habits of your fish. Explore the Ocean Nutrition Feeding Guide to find feeding recommendations, dietary information and suitable foods for popular freshwater and saltwater aquarium species.

Choosing the Right Food for Your Aquarium Fish

Every aquarium fish has different nutritional needs. Species may naturally feed on algae, plants, plankton, crustaceans, small fish or a combination of food sources. Understanding these natural feeding habits can help you choose an appropriate diet for the fish in your aquarium.

Ocean Nutrition offers foods for freshwater and marine aquarium species in a variety of formats, including frozen foods, flakes, pellets, wafers, marine algae and specialty foods. The best choice depends on the species, size, natural diet and feeding behavior of your fish.

Freshwater Fish Nutrition

Freshwater aquariums can contain species with very different feeding behaviors. Bettas and many Cichlids may benefit from protein-rich diets, while Plecos and other grazing species may require foods containing plant and algae-based ingredients. Community aquariums may require several food types to accommodate fish that feed at different levels of the aquarium.

Marine & Saltwater Fish Nutrition

Marine fish can range from algae-grazing herbivores to highly specialized carnivores and omnivores. Tangs and Rabbitfish, for example, have different feeding requirements from Puffers, Groupers or many reef fish. Providing a varied diet appropriate for each species helps support healthy growth, coloration and activity.

Dry & Frozen Aquarium Fish Food

The form of food you offer can be just as important as its ingredients. Flakes and pellets provide convenient everyday feeding options for many aquarium fish, while sinking foods and wafers can help reach bottom-feeding species. Frozen foods provide additional variety and can help reproduce feeding experiences closer to the natural diets of many freshwater and marine fish.
