CATDOLL : CATDOLL: Can moon jellyfish be raised in tap water?

1. Can moon jellyfish be raised in tap water?

No, high-quality sea salt supermarkets have 1. Use a 4-liter drinking water bucket to buy community coins or

Or fill tap water into an old tank (use plastic

The same applies to storage boxes). If it is tap water, it needs to be aerated.

More than 24 hours.

2. Use an electronic scale to weigh salt: 1 liter of water * 33.5 = grams

3. Put a small pump in the old tank, turn it on, and slowly pump the salt

Pour it in, generally after 24 hours, raise the temperature to 26-

27 degrees can be used directly

If you are just starting a new tank, you can directly dissolve salt in the tank.

Length*width*height=liters, liters*33=grams (first less

Add some, measure with a hydrometer after finishing, and then adjust

）

2. Can I use salt water instead of sea water if I don’t have sea water at home?

First of all, let me complain that it is the moon jellyfish =-=; then, marine coelenterates rely on seawater to maintain osmotic pressure and enrich certain ions that are less abundant in seawater, artificially preparing salt water to cultivate moon jellyfish =-=

1. Ensure that the salt water and sea water are strictly isotonic.

2. The oxygen supply must be sufficient (jellyfish have no respiratory organs and the gas exchange efficiency is not high)

3. Provide various nutrients needed for its growth, including organic nutrients (food) and inorganic nutrients (certain salts other than sodium chloride in seawater, etc.).

I suggest not using iodized table salt to make brine, but using industrial-grade sodium chloride =-=. Also, marine aquaculture does not require feeding or requires less feeding, because seawater contains its own food, while saltwater aquaculture does require feeding.

3. Can moon jellyfish be kept in a goldfish tank at home?

No, you can't, because the edges and corners will pierce you, because 98% of the jellyfish's body will sleep! Round ones might be okay, but rectangular ones are definitely not okay!!!

4. How to raise small jellyfish in the sea

The tank needs to be illuminated with a strong light of 800W for a long time to replenish their energy. In addition, a thermostat should be placed in the tank to keep the water temperature at around 25 degrees Celsius, otherwise their "survival" will be in trouble. In addition, the water should be changed every week or so to prevent dust and microorganisms from blocking the jellyfish and fish from receiving energy and affecting their movement speed.

Small jellyfish like to eat plankton, while large ones are fish (preferably alive). The water temperature for jellyfish should be low, otherwise they will die. Use water from the place of origin. For example, if you fish from the sea, use seawater. When buying jellyfish, be sure to buy non-toxic ones (the jellyfish in the jellyfish lake are not toxic), otherwise it is no joke if it stings you.
