I bought a few jellyfish, how should I keep them?

Jellyfish is a very beautiful aquatic animal. Its body shape is like a transparent umbrella. The diameter of the umbrella varies. The diameter of the umbrella of a large jellyfish can reach 2 meters. The main component of the jellyfish body is water. It is composed of two germ layers, the inner and outer germ layers. There is a very thick mesoglea layer between the two layers. It is not only transparent, but also has a floating effect. So how do we raise jellyfish? Here are some specific methods for you.

1. Install the jellyfish tank according to the instructions, and then add seawater. Jellyfish protective agent needs to be added to natural seawater. It needs to be precipitated for about 24 hours before use. Artificial seawater is added to pure water at a ratio of 1:0.032 (do not add edible salt). The salinity of seawater is generally 3.5%.

2. After putting seawater in and running the jellyfish tank for 24 hours, put the jellyfish into the tank. First, warm it up for 10 minutes, and then add water three times before pouring the jellyfish into the jellyfish tank (be careful not to expose the jellyfish to the air).

3. The next step is the daily maintenance of the jellyfish. Do not feed the moon jellyfish on the first day after entering the tank. Feed it once a day from the second day. You can choose brine shrimp larvae or jellyfish-specific liquid feed when feeding. Feed each jellyfish 1/3 teaspoon of brine shrimp larvae hatched from shrimp eggs or 2 drops of liquid feed each time. Turn off the water pump (circulation system) when feeding to facilitate the jellyfish to eat. After finishing, clean up the remaining food in time to avoid water quality deterioration. (For the hatching of brine shrimp, see the corresponding entry in Baidu Experience) When the stomach cavity of the jellyfish turns orange-red, it means that the jellyfish is full. Do not feed it too much to avoid the jellyfish dying of bloating.

4. Jellyfish do not like too frequent water changes. The principle of changing water for jellyfish is to change the water in small amounts and less times. Change the water once a week in summer and once every two weeks in winter. Each time you change the water, you only need to change 1/10 of the total water volume, and the water quality and salinity must be the same as the original water. The replaced water can be used for hatching brine shrimp.

5. Moon jellyfish can survive in water temperatures of 15-30°C, and the optimal temperature is 25°C. Avoid direct sunlight and do not place the jellyfish tank directly above the heater.

6. Moon jellyfish do not have high requirements for light sources. As long as they are not exposed to direct sunlight, there is basically no big problem. If it is the Australian spotted jellyfish, sufficient light must be ensured.
