CATDOLL : CATDOLL: Can jellyfish be kept together with goldfish?

1. Can jellyfish be kept together with goldfish?

I believe you! This jellyfish lives in rivers! It is freshwater!

2. Can jellyfish be kept together with red dragon fish?

No, the dragon fish will eat the jellyfish

3. What kind of jellyfish is suitable for koi fish tanks?

Moon jellyfish in an aquarium. As shown in the picture above, jellyfish are usually kept individually.

If you want to keep jellyfish and tropical fish together in a fish tank, you must first determine a few key points:

It is better not to keep them together. Besides the fact that young or small fish may be stung to death by jellyfish, there will be a drama of the big eating the small in the fish tank every day until the other is eaten up.

Raising jellyfish and tropical fish together can make both of them live well. For example, the mixed culture method of fresh water and sea water has been carried out in water pipes. This mixed culture method uses the habits of fish's eurythmia, so that special fish species can be raised together without problems. The mixed culture method of fresh water and sea water requires a slow increase in the salt proportion, and cannot be directly increased to the proportion of real seawater. Edible tide sea bream is cultivated in this way, so it should be feasible to raise tropical fish and jellyfish together, but it should be noted that the size of the two should not differ too much.

If they are creatures from two different waters, the jellyfish sold on the market generally come from seawater and are mainly fed with liquid feed, while many tropical fish are freshwater species and can only live in ordinary aquariums, unless they are fish or jellyfish near the seaport and live at the junction of freshwater and seawater, they have a chance to be raised in freshwater and seawater. However, because the salt ratio is slightly different for fish and jellyfish species, although there are jellyfish that are freshwater and some tropical fish can also live in water with different salinities, it is recommended not to keep them together before the relationship between their food chains is clear!

As mentioned above, keeping them together is just a matter of survival of the fittest. Jellyfish are beautiful but difficult to keep. What I often see is that they become feed for fish directly, so it is best to first confirm the relationship between the species and the food chain.

In the natural environment, the lifespan of jellyfish is about one year, and in an artificial aquarium, it usually lasts for several years, depending on the care taken. Jellyfish are simple single-celled organisms, and if they are well cared for, they can live for at least three or four years. Most jellyfish are poisonous, so it is recommended to keep them individually, because if small fish are touched by the tentacles, they will become the jellyfish's food.

Whether jellyfish should be raised in seawater or freshwater is related to whether tropical fish can also be raised in seawater or freshwater. The two organisms cannot coexist in water with different pH values ​​and will inevitably be damaged. Unless they can be separated in medium to large fish tanks as shown in the following pictures, allowing jellyfish and tropical fish to survive in their own areas, otherwise it is more likely to lead to cannibalism.

Draw the desired pattern on the acrylic spacer and make sure that the size is suitable. Place it away from the suction port of the water filter motor.

Use an electric drill to drill holes in the designed pattern on it so that the water in the fish tank can flow.

Place the dug partition in the fish tank and fix it with silicone resin.

After the setup is completed as shown above, it is recommended to confirm the positions of the fish and jellyfish on each side.

Add water and decorations, install sand and live rock, and adjust water temperature and salinity.

The basic materials needed for jellyfish and tropical fish are as follows:

A 9W blue-white light, 1 kg of seashell sand, 1 acrylic partition*1 external water filter*1 live rock, and 1 kg of nine-in-one marine fish feed. The fishier the feed, the better. Both fish and jellyfish can enjoy it at the same time. Just remember to grind the feed for jellyfish.

When feeding jellyfish, add seawater, use a dropper to suck up the feed, and gently place it on the jellyfish's tentacles. After the jellyfish finds the food, it will produce digestive juice to digest the feed, and the feeding will be successful!

While the jellyfish are swimming freely in the fish tank, the tropical fish can be kept on the other side of the acrylic partition. Remember that the water surface should be slightly lower than the partition to prevent the fish or jellyfish from taking the opportunity to swim into the other's sphere of influence. In this way, there will be no problem for tropical fish and jellyfish to coexist in the same fish tank!

4. Why do jellyfish have to coexist with conchs?

Jellyfish can move freely. During the development of jellyfish, fertilized eggs develop into larvae, and larvae develop into hydras. Hydras can only live a fixed life, attached to some objects, and in a group, and then develop into jellyfish and live freely. Jellyfish produce reproductive cells, which combine to form fertilized eggs and develop into hydras, and the cycle continues.
