Jellyfish are beautiful aquatic creatures in the ocean. How to raise jellyfish?

After installing the jellyfish tank according to the instructions and soaking the tank, add seawater. Jellyfish protectant needs to be added to natural seawater. It needs to be precipitated for about 24 hours before use. Artificial seawater is added with artificial sea salt (do not add table salt) in a ratio of 1:0.032 in pure water. The salinity of seawater is generally ocean elves. Many people want to raise jellyfish but are deterred from it because jellyfish are poisonous. If stung by a jellyfish, symptoms such as skin redness or muscle pain may appear in a short period of time. In severe cases, breathing difficulties, shock and even death may occur.

So which kind of jellyfish should we choose? If there is no water flow, you can change a small amount of water and use the water flow to flush the small jellyfish, and the small jellyfish will swim. But you must pay attention to the fact that the temperature of the water you bought or the salted water and the water in the jellyfish bottle should not be too different, otherwise the small jellyfish will not adapt well and may even die. The survival temperature of jellyfish is 20-33℃, and the best breeding temperature is between 22℃-26℃. Usually, the water temperature should be kept below 28℃; the survival temperature of colored jellyfish is 20-36℃.

The best breeding temperature is between 22℃-26℃, and the water temperature should be kept below 32℃. Moon jellyfish is also a good choice. Compared with other jellyfish, they are relatively less toxic. They like to live in a 25-degree water. They have high requirements for food. For those who want to get moon jellyfish, I, the editor of Aipet.com, will tell you how to raise them. However, you should keep the jellyfish bottle in the refrigerator; take it out when you want to watch it, and put it back in the refrigerator when you don’t want to watch it. The temperature is too high and the jellyfish will die easily. Then prepare the water change salt. Because jellyfish will not adapt to new seawater, you should prepare the seawater first and change the water for the jellyfish later.

Normally, you should keep the jellyfish bottle in the refrigerator. When you want to watch it, take it out. When you don't want to watch it, put it back in the refrigerator. The temperature is too high and the jellyfish will die easily. Then prepare the water change salt. Because jellyfish will not adapt to new seawater, you should prepare the seawater first and change the water for the jellyfish later.

Jellyfish are marine creatures, so they must be raised in seawater. The water should be changed every week or so to prevent dirt and microorganisms from blocking the jellyfish and fish from receiving energy and affecting their movement speed. Be careful not to touch the jellyfish when changing the water. Don't rush when adding water, but be slow.

Jellyfish should be kept in a relatively large fish tank. The water in the tank should be changed frequently, and there should be sufficient oxygen. A few small fish should be placed in it.

Jellyfish are marine creatures, so they should be kept in seawater. Generally speaking, you must change the water when raising jellyfish, and you can change 1/3 of the water every two weeks. This is to prevent pollutants in the water from blocking the jellyfish's receiving ability and affecting the jellyfish's swimming speed. You can buy a special aquarium to raise jellyfish and install a thermostat. The temperature can be adjusted to around 25 degrees.

How to breed jellyfish?

The breeding of jellyfish will also vary depending on the species. There are the following points in the breeding of jellyfish:

1. Water quality

First of all, the bubbles and water flow in the jellyfish breeding tank are the most important issues that need long-term attention, and then there is the importance of aeration. The water quality is very important in the process of breeding jellyfish. We can gradually add nitrifying bacteria to the jellyfish aquarium in small amounts and multiple times to help establish the water quality system. The effects of bubbles on different jellyfish are also different. These jellyfish are also not suitable for growing in a strong water flow environment. Too strong water flow will separate the wings and mouth of the jellyfish.

2. Water temperature

The most suitable temperature for raising jellyfish is 25 degrees. A water chiller is an essential tool for raising jellyfish. If the temperature is too high, the activity of the jellyfish will decrease, and then they will sink to the bottom of the tank and die.

3. Change the water

The amount of water to be changed varies depending on the number of jellyfish, the size of the tank, etc., but you should change the water at least twice a month. Try not to hurt the jellyfish, do not suck up the jellyfish when draining, avoid the generation of bubbles when adding water, and do not add water too quickly.

4. Co-culture with other organisms

Some aggressive fish and crustaceans will snatch the bait attached to the jellyfish or attack the jellyfish directly, so try to choose gentle fish species. As for soft-bodied fish, although they have low mobility, their poisonous tentacles are masters at catching jellyfish, and jellyfish may be preyed on at night.

5. Jellyfish Feed

Jellyfish feed on plankton in the water, but in an aquarium, it is impossible to provide water full of plankton and organic matter. Therefore, the bait is mainly brine shrimp. It is also necessary to supplement jellyfish liquid feed, seawater trace elements, and seawater rotifer feed specifically for soft bodies. Jellyfish have a simple digestive structure and can also be fed with this easily decomposed feed. When the digestive organ and mouth in the jellyfish's wings turn orange, it means that the jellyfish is full. Please do not feed too many times or in too large quantities, because the water quality is easy to deteriorate.

6. Light

There are symbiotic algae "zooxanthellae" in the jellyfish's body. The nutrients produced by these algae through photosynthesis are supplied to the jellyfish, and the nitrogenous waste produced by the jellyfish's metabolism is provided to the unicellular zooxanthellae in the body. The relationship between the two is interdependent, so light is important in jellyfish aquariums. Providing jellyfish aquariums with appropriate coral basket lights can provide unicellular zooxanthellae for photosynthesis. With coral lights as the main source, the lighting time does not need to be specially strengthened.

First, buy jellyfish. The best size of jellyfish is 5cm. Jellyfish that are too large spend most of their lives in farms, and jellyfish that are too small are less ornamental. After installing the jellyfish tank according to the instructions and soaking the tank, 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%. After putting seawater in and running the jellyfish tank for 24 hours, the jellyfish enter the tank. First, warm it 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). 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. When feeding, you can choose brine shrimp larvae or liquid feed for jellyfish. 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. Clean up the remaining food in time after the feeding to prevent the water quality from deteriorating. When the stomach cavity of the jellyfish turns orange-red, it means that the jellyfish is full. Do not overfeed to prevent the jellyfish from being overfed. Jellyfish do not like to change water too frequently. Change the water for jellyfish based on the principle of small amounts and few 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 and salinity must be the same as the original water. The replaced water can be used for the hatching of brine shrimp. The moon jellyfish can survive in a water temperature of 15-30℃, and the optimal temperature is 25℃. Avoid direct sunlight and do not place the jellyfish tank directly above the heater. The moon jellyfish does not require much light source. As long as it is not directly exposed to sunlight, there is basically no big problem. If it is an Australian spotted jellyfish, sufficient light must be guaranteed.
