How can you have jellyfish as pets

Keeping a jellyfish as a pet: what to watch out for

Jellyfish move leisurely and gracefully through the water at the same time. So it's no wonder that animals are becoming increasingly popular as pets. An aquarium with jellyfish, at best illuminated, becomes an exciting and calming eye-catcher in every room. For the well-being of the animals and the long-term enjoyment of them, species-appropriate husbandry is particularly important. Not all jellyfish species are suitable for life in the aquarium.

  • Jellyfish are swarm animals and should therefore not be purchased individually. You therefore need enough space for several animals of the same species.
  • Only those types of jellyfish that can be drifted by the current are suitable for life in the aquarium. Specimens that can be blown by the wind on the surface or live on the bottom are not for the aquarium.
  • A popular species for keeping in the aquarium is the ear jellyfish (Aurelia aurita). It doesn't take up too much space and has few demands on the water temperature. The lighting conditions, which can vary depending on the room and lighting, don't bother you much.
  • Other jellyfish species are much more demanding. You should therefore always find out about the necessary requirements for keeping from your specialist dealer. Please note that for some specimens you will need extensive experience in the field of aquaristics.
  • Also note that there are freshwater and saltwater jellyfish. The vast majority are made up of the latter. In any case, you need to choose the water according to the type.
  • Jellyfish have a life expectancy of a few months to about a year. Since they consist almost entirely of water, they dissolve in the aquarium after they die.
  • Jellyfish feed on plankton and other tiny particles in the water. They don't do this when they're hungry, they do this all the time. Feed 2-4 times a day to keep the food supply in the water constant. Always keep an eye on the water quality.
