Frozen tropical fish food provides an easy and interesting way to enrich the diet of aquarium fish, mimicking their natural habitat and perfect for finicky feeders or conditioning new breeding fish into shape.
Frozen foods for aquarium fish come either as cubes or larger frozen slabs that have been irradiated to prevent bacteria growth. Smaller species enjoy smaller treats like brine shrimp and tubifex worms while larger specimens prefer frozen cocktail shrimp and prawns.

Freeze-Dried Foods
Freeze-drying foods is an effective way to preserve their flavor, texture and nutritional content while simultaneously eliminating much of their moisture content – this reduces or prevents spoilage caused by bacteria or microorganisms and allows long-term storage without refrigeration.
Freeze-drying food may take four to two days, depending on its type and size. Food is stored in airtight containers during this time to protect from water vapor or oxygen absorption and ensure quality final products. Some freeze-dried products are packaged directly for consumers while others may be sent off to a secondary processor to be added into other recipes or food products like cereals and snack mixes.
Freeze-dried foods are compact and lightweight, making them simple to store and transport. Their long shelf-life makes them great for camping trips or emergency food supplies, while many freeze-dried items can even be rehydrated using just water to create delicious meals!
Frozen Crustaceans
Crustaceans such as lobster, crab and shrimp are popular food sources for fish aquariums. Some whole frozen crustaceans can be frozen whole and then thawed out before use; other frozen crustaceans may need to be chopped before feeding into an aquarium environment, or packaged as pre-portioned foods like frozen brine shrimp.
Frozen krill and clams are favorites among larger carnivorous fish, along with frozen mysis shrimp and silversides. These foods can often be found packaged as convenient frozen cubes or slabs.
Tiny fry and fingerlings of various species enjoy feedings such as bloodworm, tubifex and frozen brine shrimp (Artemia nauplii). These foods dissolve easily in aquarium water and are readily accepted by most species of fish species as a highly nutritious alternative to standard flakes. Frozen brine shrimp helps improve coloration as well as provide additional protein; all should be provided no more frequently than once or twice each week as treats for maximum effectiveness.
Frozen Meaty Foods
Frozen foods typically feature whole ingredients packed with nutrients before being flash frozen to preserve both taste and nutrition. Frozen items typically consist of larger-than-flakes food items sold as frozen slabs or trays; larger fish such as stingrays and arowana may need human-sized seafood like frozen cocktail shrimp, fish filets, prawns for optimal growth while monster pufferfish require chewy clams and oysters to help with filing down their ever-growing teeth.
Easy and cost-effective supplements for tropical fish diets, these foods make great additions to a tropical fisher’s feeding regime. Fish easily consume these items, helping increase metabolisms, energy levels, immune health and vibrant colors in their fish.
Ocean Nutrition offers several frozen food formulas tailored specifically to pygmy angelfish (centropyge sp). Their Pygmy Angel Formula features marine algae, Spirulina, fresh seafood, vitamins and pigments that promote health, vitality and coloration in these species of angelfish.
Frozen Vegetables
Frozen vegetables can be used in soups, stews and casseroles as well as smoothies, as well as to create smoothies. Frozen veggies can also be cooked by steaming, sauteing, boiling, microwaving or frying – though fresh produce might taste better when used for salads with strong flavors than frozen does in such applications. Frozen vegetables also make great additions to soups stews and casseroles!
Fatty foods such as shrimp and krill can serve as treats for larger fish such as pufferfish. Pufferfish require hard shelled foods like frozen clams and oysters in their diet to file down their ever-expanding teeth, making frozen seafood treats like these an excellent solution.
Frozen vegetables can be quickly defrosted by placing them in the refrigerator, cold water or warm water bowls, or being placed into the microwave according to package instructions for cooking time and temperature. Certain food such as tomatoes and cucumbers do not freeze well as they lose texture and flavor from being frozen, however.
