Jellyfish Foods

Jellyfish Art provides a Frozen Jellyfish Food specifically formulated for jellyfish made from plankton high in HUFAs (Highly Unsaturated Fatty Acids), which are essential for proper nutrition. We strongly suggest only feeding jellyfish with our recommended food. Other fish foods that claim to be suitable for jellyfish are often low quality. Follow the feeding guide to properly feed your jellyfish.

In the wild, most jellyfish feed on plankton, which is made up of thousands of microscopic species of swimming animals. Jellyfish only eat zooplankton (animals that eat plants or other animals), not phytoplankton (plants that produce their own energy from the sun). Some species of jellyfish, such as the Upside Down Jelly, host symbiotic algae within their oral arms. This algae provides extra nutrition to the jellyfish by producing organic material through photosynthesis. Many species of jellyfish feed on other species of jellyfish. For example, the Sea Nettles feed on Moon Jellyfish.

Jellyfish can also be fed live food, such as baby brine shrimp. This food is highly nutritious and recommended especially for sick or struggling jellies. Public aquariums have a full time staff, so they almost always hatch their own baby brine shrimp to feed to jellyfish. Depending on the species of jellyfish, sometimes public aquariums also feed the jellyfish rotifers, blended krill, chopped fish, and other foods. Public aquariums rely on these time-consuming foods because they often keep exotic species, breed jellyfish and run experiments. However, hobbyists can use Jellyfish Art's frozen and live food to suit their jellyfish's needs.
