A jellyfish that is not moving is dead. When a jellyfish dies, it slowly turns into water, because a jellyfish's body is 90% water.

You can find a clean thing to move it to see if it still moves. In order to avoid such a situation, when carrying out feeding, make sure that the temperature is 25 ℃, if the temperature is too high it will reduce its mobility, thus it will sink and thus die. If the water quality deteriorates, you should change the water in time, and be careful not to hurt the jellyfish when you change the water.

Precautions for breeding jellyfish:

1. Water quality requirements:

Jellyfish is a marine organism, so it is necessary to seawater breeding. Generally in the feeding time also need to change the water, two weeks to change 1/3 of the water can be, this is to avoid the pollutants in the water to block the jellyfish to receive the ability, but also will affect its swimming speed.

2. Preparation for breeding:

You can buy a special aquarium for breeding jellyfish, and then put in a thermostat, the temperature is adjusted to about twenty-five degrees can be.

3. Food preparation:

Worms, shrimp meat can be fed to jellyfish, plankton is their best food. If you see the mouth change color during feeding, this is a sign that it is full. You can use this information to determine the quantity of each feeding to avoid overfeeding and causing water pollution.

4. Light source management:

Jellyfish generally need a light source, the jellyfish's body is the existence of a single cell, and it is necessary to carry out photosynthesis, so that the oxygen can be transmitted to the jellyfish, and jellyfish waste produced by a single cell of food, so they are dependent on each other.
