CATDOLL : CATDOLL: Are pet jellyfish easy to keep?

1. Are pet jellyfish easy to keep?

Very easy to keep... Just change the water. Be careful, it is easier to die when it faints.

2. Can the jellyfish sold online be kept alive? What do I need to keep jellyfish alive?

Some jellyfish are electric and some are poisonous, so it is best not to keep them.

3. 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.

4. I want to raise jellyfish. Is it possible? Please give a professional answer.

Sea jellyfish have high requirements for salinity and cannot be properly regulated. Freshwater jellyfish are easy to raise, but difficult to get.

It is also difficult to buy in the flower and bird market, so it is better not to raise it.
