The jellyfish does not recognize its owner. Jellyfish are intestinal animals, which are very low-level animals. They have no nerve center, so it is impossible to establish feelings with them. They have no sense organs, let alone hearing organs, only sensory cells and tentacles. Normally even if you feed them, they won't remember you at all.

The correct way to raise jellyfish:

1. Choose a suitable jellyfish and pay attention to whether it is poisonous. If someone with a sensitive constitution is accidentally exposed to a jellyfish, they may still experience itching and redness from contact with the stinging cells on the jellyfish, so be very careful.

2. Jellyfish are marine creatures. Change the sea water for jellyfish every week or so to avoid dust and microorganisms from hindering jellyfish and fish from receiving energy and affecting their movement speed. If we can't get sea water, we can also use fresh water. Be careful not to touch the jellyfish when changing the water, and add water slowly rather than quickly.

3. Plankton such as algae, artemia, and shrimp are the favorites of most jellyfish. When the jellyfish's digestive organs and mouth turn orange, it means the jellyfish is full. The frequency and amount of food added should be controlled and should not be too much, otherwise the jellyfish will not be able to finish it and the food will rot, causing the water quality to deteriorate.
