Reef Plankton

Scientific name: Calanus finmarchicus

Excellent for Reef Tanks

Reef Plankton feeds fish, corals, and invertebrates simultaneously in your reef aquarium. They stimulate appetite and are eagerly eaten by finicky marine fish, such as butterflies and anthias. Reef Plankton provides essential nutrients that help maintain high energy levels and vigor in your fish and invertebrates.

Recommended for:
Reef Inhabitants: Anemones, Corals, Scallops, Shrimp, Anthias, Butterflies, Clownfish, Gobies, Mandarins, Pygmy Angels, Filter Feeders and others.


Feed often, but only what can be consumed in three minutes. Remove any uneaten food. Never overfeed. No thawing or rinsing required. Keep frozen.

Microwaving or thawing in hot water is not recommended, as this breaks down the nutrients contained in frozen fish food.

Copepods, copepodites and copepod nauplii from the Calanus species, a much larger copepod (compared to our Cyclops copepods) inhabiting cold marine waters. Calanus are an important member of the zooplankton community and as such form a prey species for a wide variety of marine organisms, from fish larvae to plankton sieving whales. Due to their grazing on marine phytoplankton Calanus copepods contain very high levels of the (for fish) important polyunsaturated fatty acids EPA & DHA as well as various carotenoids (natural pigments). Calanus form an excellent food source for feeding marine fish fry, smaller marine fish and marine invertebrates. They might be too big though for feeding some corals.
