There are a lot of water fleas in my shrimp tank. Do goldfish eat water fleas?

They can eat it and they like it very much. If you are planning to put the goldfish into the shrimp tank to let it eat, I suggest you not to do this because goldfish will eat shrimp. I suggest you use a plastic dropper to suck out the water fleas and feed them to the fish. This will not cause any trouble.

Most fish eat Daphnia, but they also eat the newly hatched shrimps... So if you can avoid adding fish, don't do it. Daphnia won't affect the shrimps...

Eat, it will be nutritious.

Of course~~~

Tips for Keeping Goldfish

Red Pearl

Goldfish are not unfamiliar to us. They can be said to be very common aquatic animals. There are also many families raising goldfish. Many children find it fun and keep feeding goldfish food. This method is wrong and parents should stop it. Excessive feeding may very likely cause the death of goldfish. So, what are the correct ways to feed goldfish?

1. Feeding Goldfish

1. Larvae stage

Goldfish are oviparous animals. After the fry have just emerged from the eggs, they cannot eat food. There is a large yolk sac in the abdomen. In the first 2 to 3 days after hatching, they rely on the nutrients in the yolk sac to survive. When the nutrients in the yolk sac are exhausted, the fry have to obtain food from the outside environment, which is the beginning of the goldfish's lifelong feeding activities.

Fry fish are different from adult goldfish. Since they do not have mature digestive organs, they need to eat relatively small plankton, such as rotifers and paramecium. Slightly larger fry can be fed with bloodworms, such as cladocerans, copepods, etc. In artificial breeding, they can also be replaced with egg or duck egg yolk crumbs. The feeding of fry directly affects whether you can get high-quality goldfish seedlings in the future.

2. Fry stage

Slightly older goldfish can be fed with animal baits such as water fleas, jumping water fleas, earthworms (water worms), snail meat, shrimp meat, or other animal viscera. Plant baits include floating algae (golden algae, yellow algae, green algae, dinoflagellates, diatoms, and blue algae). When these algae gather into clumps, they can be preyed on by goldfish. Vegetable foods, such as spinach, cabbage, lettuce leaves, carrot cubes, sweet potato cubes, etc. It is generally more effective to feed goldfish when they are hungry. Vegetables should be free of pesticide pollution to avoid poisoning.

3. Semi-adult and adult stages

At this stage, we can mainly use artificial compound feed, which contains more than 40% animal protein (fish meal, silkworm pupa meal, etc.), 20% soybean meal, 10% corn meal, 30% flour and wheat bran, and some trace elements. In terms of nutrition, it can basically meet the needs of goldfish over 5 cm.

2. Precautions for raising goldfish

1. Water skills

1) First clean the transparent fish tank (other containers are also OK, but make sure they are transparent)

2) Use soda water. If you don't have soda water, you can use cold boiled water instead. But remember not to use tap water, because tap water contains disinfectant chlorine, which the goldfish cannot handle.

3) Add as much water as possible to ensure good oxygen content and sufficient freedom for the fish. It is best to buy a small air pump specifically for fish farming.

2. Breeding skills

1) If there is no condition to maintain the water temperature in the fish tank, you should always give the goldfish enough sunlight during this cold winter.

2) Put some white rice stones and some water plants in the fish tank, but remember that the water plants must be appropriate.

3) You can feed some fish worms or white flour buns, but feed less and more frequently each time.

Also, please note that goldfish are particularly susceptible to white spot disease (a parasitic disease). If you find such things on the fish or scales fall off and there are wounds, remember to go to the flower and bird market to buy a kind of "yellow powder" (mainly for anti-inflammatory), and then drop some methylene blue medicine (mainly for parasite removal) when changing the water for the fish. With your careful care, the goldfish will definitely bring you equal happiness.

3. Feeding Methods

First, prepare the fish tank and dry the water in advance. If you want to lay sand and plant grass, you need to add water slowly after everything is ready. It takes about one or two days to dry the water. Then put the plastic bag containing the goldfish and the "old water" into the aquarium, so that it hangs in the middle and upper layers of the water body. After about half an hour, it is estimated that the water temperature in the plastic bag is close to that in the aquarium. At the same time, add 1 teaspoon of salt to the water to sterilize it. Wait for the fish to adapt to the aquarium for 1-2 days before feeding. If you need to increase the stocking amount, you should first place the new fish in another container and raise them alone for 7-10 days. After observing that the fish are indeed disease-free, put them together with the fish in the original aquarium to avoid bringing in pathogens.

1. Feeding method

Goldfish are usually fed with artificial and natural baits. Feeding must be done at a strict time and quantity to keep the water fresh. Generally speaking, feeding should be done 1-2 times a day, once in the morning and once in the evening. It is better to feed once in the evening in the morning rather than late. In addition, the time, frequency and quantity of feeding should also be determined according to the following principles:

(1) When the weather is clear, the sun is warm and the wind is gentle, there is sufficient dissolved oxygen in the water and the water temperature is suitable, you can add more bait.

(2) When the water is clear and the fish have a strong appetite, you can add more bait.

(3) If the fish is sick or the species is delicate and precious, you should use less coarse bait and more fine bait instead.

To tell whether the goldfish is hungry or full and how well it is digesting and absorbing food, you can tell by the color of its excrement. If the excrement is green, brown or black, it means the fish is eating properly and absorbing food well. If the excrement is white, it means the fish is overfed.

2. To raise goldfish indoors, you must first solve the lighting problem:

Because the beauty of goldfish lies not only in its shape but also in its color. To ensure the bright color, the fish body must be exposed to strong light, otherwise, the fish body color will become increasingly dim and it is easy to get sick. Therefore, the place where goldfish are fed should have sufficient light, preferably ultraviolet light.

If the temperature is suitable, you can place the fish tank on a balcony or in front of a window during the day to ensure sufficient light. Therefore, if you master the temperature suitable for the growth of goldfish and ensure sufficient light, raising goldfish indoors will have a great guarantee.

In short, you must use the correct method to raise goldfish. Don't feed goldfish blindly. Change the water regularly and clean the debris in the bathtub to ensure the health of the goldfish.

I will tell you the key points of raising goldfish at home: this is a summary of my experience in raising goldfish for more than 10 years, and it is not a long article downloaded from the Internet. It may be helpful for you to raise goldfish in the future.

1. Feeding: All feeds are nutritious animal feed and white sesame. Animal feeds include water fleas, earthworms, mealworms, caterpillars, and skinworms. The main feeds are earthworms and white sesame. Both red and black earthworms can be fed. Raw white sesame can be fed as the main food. White sesame is easy to buy. Goldfish love to eat it, it is easy to digest, and it is not easy to pollute the water quality. Do not feed the inferior goldfish feed you buy. Because this kind of feed has too much starch, poor nutrition, difficult to digest, and easy to pollute the water quality. Goldfish will be malnourished after eating it, and the growth of goldfish will be slower and they are prone to diseases. As long as goldfish eat easily digestible food, they will not die of bloating. When to feed? Generally, once in the morning and afternoon every day. It is not advisable to feed more, and feed until all the food is eaten. Otherwise, it will pollute the water quality.

2. Light: It is best to place the fish tank in a place where there is sunlight for 1-2 hours. In this way, the ultraviolet rays of the sun can be used to sterilize. It plays a role in disease prevention. This can reduce diseases. Try to prevent fish diseases as the main method and use medicine as the auxiliary method. At the same time, due to photosynthesis, the color of the fish body is also brighter and more beautiful.

3. Change water: Change water frequently to increase dissolved oxygen in the water. When changing water, only one-third to one-quarter of the water should be changed. Do not change a lot at once, or the fish will not adapt. It is very important to keep the water in the aquarium clear. Fish can only grow and grow fast if there is sufficient dissolved oxygen in the water. Otherwise, they will stop growing or even die. There is no definite answer to when to change water. It can be determined according to the water quality. Change water more often if the water is turbid, otherwise change less often.

4. Stocking density: Because the rectangular aquarium for domestic use is small in size, it is not advisable to raise too many fish. It is better to raise less rather than more. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, 6 to 8 small goldfish of 5 to 7 cm in length can be raised. For example, in a round glass tank with a diameter of 26 cm and a height of 13 cm, 4 to 6 small goldfish of 4 to 6 cm in length can be raised. Adult fish with a body length of more than 8 cm should not be raised in a small glass tank, but should be raised in a large glass tank or a ceramic tank, and equipped with a small oxygenator to prevent hypoxia. These stocking densities are only reference numbers, and they should be determined by the water temperature, the strength of the fish, and the quality of the water. They cannot be mechanical. Generally speaking, the larger the fish, the fewer the number of fish to be raised; raise more in winter and less in summer; raise more when the water temperature is low and raise less when the water temperature is high. If you master the above points when raising goldfish at home, you will be able to keep them healthy and lively, colorful, swimming in the water, and being loved by people, so that you will never get tired of watching them and have endless fun. You will definitely be able to raise them well, and I wish you success.

Try to put it in a large tank, preferably in a sunny and ventilated place. Don't always think about changing its water, unless it is really about to be deprived of oxygen. Don't feed it too much food, it will be bloated to death. Goldfish are not afraid of starving to death, but they are afraid of being bloated to death.
