Unlike many traditional aquarium foods, Calanus is naturally high in omega-3 fatty acids, proteins, and carotenoids that support fish health, improved colouration, and strong immune systems. Because of its exceptional nutritional profile, Calanus is popular among reef hobbyists who want to provide a more natural and beneficial food source for their marine aquarium inhabitants.

At iReef, we stock Calanus products designed to provide high quality nutrition for reef aquariums.

Natural Marine Nutrition

Calanus finmarchicus is a small marine copepod that forms part of the natural food chain within ocean ecosystems. This makes it an excellent food source for marine fish and other reef organisms.

Because Calanus is harvested and preserved to retain its natural nutritional value, it provides a food source rich in essential fatty acids and proteins that many aquarium fish would naturally consume in the wild.

The high concentration of omega oils helps support fish health, energy levels, and immune function while also contributing to vibrant colours in many marine species.

Ideal for Marine Fish and Reef Tanks

Calanus is suitable for feeding a wide variety of marine fish including clownfish, wrasse, tangs, angelfish, and many other reef species. Its small size and soft texture make it easy for fish to consume while still providing excellent nutritional value.

In addition to feeding fish, Calanus can also benefit reef aquariums by providing nutrients for corals and filter feeding invertebrates. Many reef hobbyists use Calanus as part of a varied feeding routine to provide a more balanced diet within their marine aquarium.

Because it is a natural marine food source, it can help replicate the feeding behaviour and diet that reef fish would experience in their natural environment.

Rich in Omega Oils and Carotenoids

One of the key benefits of Calanus is its naturally high content of omega-3 fatty acids and carotenoids. These nutrients help support fish health while enhancing natural colouration.

Carotenoids are particularly important for maintaining the bright colours seen in many marine fish and coral species. Regular feeding with nutrient rich foods like Calanus can help maintain these colours while supporting overall health and vitality.

This nutritional profile has made Calanus a popular choice among reef hobbyists who want to provide a high quality diet for their aquarium inhabitants.
