How Long Do Jellyfish Live In A Tank Or Aquarium?

How Long Do Jellyfish Live in a Tank or Aquarium?

In the wild jellyfish are very gentle swimmers, usually staying afloat and drifting along with ocean currents. So if kept in captivity, Jellyfish will need a specially designed tank to mimic this. 

The ideal jellyfish aquarium would need to have a circular flow of water to keep them in suspension, circular in shape or with rounded corners and no sharp edges where the jellyfish could get stuck. Usually these are bespoke aquariums, specially made.

Jellyfish lifespan in captivity can vary, depending on the species of jellyfish and the effective mimicking of jellyfish habitat. The most widely kept jellyfish in smaller aquariums are moon jellyfish or common jellyfish, which can live around 12 to 15 months. Typically a jellyfish kept in ideal conditions, which can be quite difficult to achieve, will live for 6-12 months. Other jellyfish species, such as blue blubber jellyfish, have a shorter lifespan.
