Things to keep in mind if you want to become a jellyfish owner

How to keep a jellyfish at home as your pet?

Jellyfish have drifted along on ocean currents for millions of years, even before dinosaurs lived on the Earth. The jellylike creatures pulse along on ocean currents and are abundant in cold and warm ocean water, in deep water, and along coastlines. But despite their name, jellyfish aren't actually fish—they're invertebrates, or animals with no backbones. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth. They eat and discard waste from this opening. 

Here are a few tips to keep in mind if you have decided to pet this magical invertebrate.

Jellyfish sometimes turn inside out, this is called inversion. It happens when the water is too cold or too hot as they are sensitive to the water temperature. In order to get them back to normal, opt for a lower temperature and the advised salinity range of the aquarium water.
