Small jellyfish can't be kept for a long time without a special container (the circular water tank that rotates with the water), but they can still be kept for a period of time, a month, if they are kept well.

It is important to pay attention to the following points for a month.

1, the temperature should not be too high, it is better to be in the early 20 s, 25 is also ok, and the high temperature will kill you.

2, not fresh water, but seawater. If there is no seawater, use sea salt or coarse salt, with a salinity of about 30.

3, need to feed, the general feed is crushed and thrown in, but it is easy to lick water, it is best to eat it alive, such as live shrimp.

4, it must be raised separately, preferably in a round cylinder or a cylinder, without running water and with fish.

5. Change the water if it is not good.
