How do you care for the small jellyfish bought by the roadside or at an aquarium?
Surely everyone has had the experience of traveling to the seaside, right? I wonder if you have ever seen this scene: at these scenic spots, small jellyfish are often displayed by the roadside for sale, and most people probably cannot resist buying one. But after buying them, they find they do not know how to keep them, so below the editor will share some breeding experience with everyone.
How to care for small jellyfish bought by the roadside
1. Water quality conditions: The jellyfish tank needs to maintain relatively good water quality. Ammonia nitrogen, nitrite nitrogen and nitrate nitrogen must not be too high, and the pH value must be kept between 7.6-8.4. Test the water quality regularly; a dedicated water quality test kit can be used for testing, and regular water changes are also essential.
2. Feeding: For home keeping of jellyfish, artificial micro-pellet feed can be used, fed 1-2 times a day. The feeding amount should be based on at least one half of the four petal-shaped stomachs of the moon jellyfish being filled with food. About 10 jellyfish of about 7 cm are fed about 1.5 grams of feed.
3. Timely water changes: For jellyfish, it is recommended to change about 1/5 of the seawater each week, and clean the particles on the filter cotton every 2-3 days. In addition, because evaporation of water in the fish tank will lower the water level, some fresh water needs to be added every 2-3 days to ensure a stable water level.
4. Disease prevention and treatment: Jellyfish can also get sick. For example, deterioration of water quality, unclean feed and drastic changes in temperature and salinity can cause bacteria to multiply in large numbers. If not treated in time, the jellyfish will be eaten up by bacteria within one or two days. The use of a special protective agent for moon jellyfish can effectively prevent and treat this.
How to care for jellyfish bought at an aquarium
1. Choosing jellyfish: The toxicity of the moon jellyfish is relatively much lower than that of other dangerous jellyfish (such as box jellyfish). Or the jellyfish in Jellyfish Lake. However, if people with sensitive constitutions accidentally touch a jellyfish, they may still develop itching and redness because they have come into contact with the stinging cells on the jellyfish.
2. Seawater breeding: Jellyfish are marine organisms, so seawater must be used to keep them. About once every week, the water also needs to be changed for them to avoid dust and microorganisms blocking the jellyfish and fish from receiving energy and affecting their movement speed. When changing the water, be careful not to touch the jellyfish, and when adding water, do not rush; it should be slow.
3. Professional equipment: Aquariums specially designed for marine organisms, especially jellyfish. Special varieties of jellyfish require a certain amount of water flow control.
4. Temperature management: A thermostat should also be placed in the aquarium to keep the water temperature at about 25 degrees Celsius, otherwise its “survival” will become a problem
5. Feeding management: Jellyfish have very high requirements for food. Zooplankton such as brine shrimp and Artemia (for Artemia breeding, please refer to other experience) are their favorites.. When the digestive organ and oral cavity in the jellyfish's bell turn orange, it means the jellyfish is already full. The number of feedings and the amount given must be controlled well, and it should not be too much, because it will easily cause the water quality to deteriorate.
Can the jellyfish being kept be eaten
There are many kinds of jellyfish. Some jellyfish can be eaten, and some cannot. For example, among the jellyfish family, the moon jellyfish and the edible jellyfish can be eaten. Other kinds cannot be eaten. After pickling, edible jellyfish is a delicacy on many people's dining tables, but it should not be eaten in large amounts. The umbrella-shaped part of the jellyfish is what we usually eat as jellyfish skin, and the tentacles of the jellyfish are jellyfish head. Usually when buying jellyfish skin, you should buy the red kind, as the taste is relatively delicate and a bit more delicious.
Is the edible jellyfish a jellyfish
The edible jellyfish is a kind of jellyfish. The edible jellyfish is classified under the class Scyphozoa, family Rhizostomatoidea, genus Rhopilema. Jellyfish include the edible jellyfish and other jellyfish. The edible jellyfish is the largest kind among jellyfish, and it is also the kind that can be eaten. Other jellyfish cannot be eaten. Only the edible jellyfish and the moon jellyfish can be eaten. The edible jellyfish is not only delicious in flesh, but also unique in taste, and it also has high nutritional value. Therefore, the edible jellyfish has become a delicious dish on modern people's tables.
That is all for the introduction of jellyfish breeding methods. I hope it is helpful to everyone. Although many people keep jellyfish now, it seems that there should not be much impact. But what cannot be forgotten is that most jellyfish are poisonous, so everyone must not touch them directly with their hands during the breeding period.
