What is the required pH level of water for goldfish?

Goldfish prefer slightly alkaline water, and the pH value of the water is more suitable between 7.5 and 8.0.

The pH value is used to represent the acidity and alkalinity of water. The higher the carbon dioxide content in the water, the lower the pH value, and the less carbon dioxide content, the higher the pH value.

Goldfish are gentle in nature, and generally have a lifespan of about 6 years, but some may live longer. Goldfish are omnivorous, carnivorous freshwater fish with well-developed throat teeth that can swallow harder bait.

Goldfish have a strong ability to adapt to water temperature, but cannot adapt to drastic temperature changes. The suitable water temperature is 18-26℃. Too high or too low temperature will affect the goldfish's feeding, growth and reproduction.

Generally, goldfish can survive in water with a pH value within the range of 5.5~9.5, with a pH value of 7.5~8.5 being the best. During the hatching period and the fry and young fish stage, the most ideal pH value in the water is 6.2~7.2.

If the pH value is low, goldfish will move slowly, have a decreased appetite, and in severe cases, stop growing.

Additional information:

There are four major types of goldfish.

1. Grass species, including grass goldfish and swallowtail grass goldfish.

2. Types of fish: high-head type: lion head, high-head ball, etc.; pearl type: including various colored pearls; fish type: various colored fish.

3. Dragon-type Chinese goldfish, varieties include various dragon-eye, sky-gazing, and hat-ball types.

4. Egg types include various types such as bubble, pompom, tiger head, red head, phoenix, etc.

Bubble fish, lion head fish and ranchu are the more difficult types of goldfish to raise. They have high requirements for light and water quality, high ornamental value and relatively high prices.

Grass goldfish and the disc-tail Chinese goldfish are the most common and relatively easy-to-raise types. They are the most common on the market and are more affordable.

If you are a beginner, you can consider raising disc tails, and then raise other species after you become more proficient.

How do I change the water for my goldfish? Is tap water okay?

Can.

Under normal water changes, especially in hot summer days, you only need to remove the feces and dirt at the bottom of the fish pond together with the old water, gently suck out 1/10-1/5 with a hose, remove the dust and floating feces on the water surface, and then slowly inject new water of equal temperature along the wall of the pond to keep the water clean. This water change method is not easy to hurt the fish, the method is simple and safe, and is most suitable for home fish tanks or small pond fish breeders.

Therefore, you can take out all the goldfish in the pond, then rotate the water in the pond into a spiral shape, and after it has been still for a while, use a rubber tube to suck out 1/3-1/2 of the dirt and stale water in the center of the pond, then inject an equal amount of new water at the same temperature, and then put the goldfish back into the original pond for breeding.

Goldfish are not easy to raise, especially when you change the water, you must pay special attention!

I also raise goldfish and use tap water. Just like the friend above said, leave it for one or two days. Don't feed goldfish too much food. If they are too full, they will die. Tips for water maintenance: Quickly establish good water quality: add water stabilizer to tap water, wait for the water temperature to be the same as the old water, and then pour it into the aquarium. Add active nitrifying bacteria, and add water clarifier to filter it after 1-2 days. After that, add artificial nitrifying bacteria every week. Goldfish-Feed Goldfish is an omnivorous fish with a wide range of food. This brings great convenience to the breeding of goldfish. However, in order to achieve a good feeding effect, you must carefully understand the habits of goldfish and the characteristics of various feeds, so that the goldfish you raise are bright in color and strong in physique. The ingredients of good goldfish feed should include: protein, fiber, fat, various vitamins and trace elements. Goldfish feed is mainly divided into two categories: aquatic biological feed and artificial synthetic feed. Aquatic biological feed includes live or dried aquatic plants and animals that goldfish can eat. Including: Daphnia (commonly known as "red jump"), sword Daphnia (commonly known as "green jump"), bloodworm (commonly known as "red worm"), water earthworm (commonly known as "nematode"), duckweed, etc. Among all aquatic biological feeds, it has been verified in practice that Daphnia has the most comprehensive nutrition and is the most suitable feed for goldfish. When fed with Daphnia, goldfish not only like to eat it, but also digest it well, and the metabolites produced are not easy to muddy the water. And the living Daphnia can also swallow the tiny dirt suspended in the water, thereby playing a role in purifying the water quality (commonly known as "taking water"). However, Daphnia generally depends on the output of nature and is affected by seasons and weather. Therefore, it can only be bought from April to November every year, which cannot meet the needs of domestic goldfish for growth throughout the year. In addition, the living Daphnia is not easy to preserve and will deteriorate in one day. Therefore, for modern people who are busy with work, it is not easy to rely entirely on Daphnia to feed goldfish. Freezing or drying can be used to extend the storage time, but its nutrients will also be lost in large quantities. The nutritional content of other aquatic biological feeds is not as comprehensive as that of water fleas, and they often carry pathogens, causing goldfish to get sick. Therefore, disinfection and alternating feed feeding methods should be adopted to avoid the above shortcomings. Feed Tips: Artificial synthetic feed is suitable for family feeding of goldfish. Flake feed is an ideal feed form. Feed ingredients are very important. Goldfish-Prevention and Treatment The beloved goldfish is sick, and the newly bought goldfish died. This is a troublesome problem that almost every beginner who raises goldfish will encounter. However, general pet hospitals do not have the business of treating goldfish, so it is very necessary to master one or two methods of treatment. Goldfish get sick because of the following factors. Environmental factors, physical damage, viral infection, etc. The following is my opinion on the prevention and treatment of these pathogenic factors: 1. Environmental factors: Goldfish live in water and are very sensitive to changes in light, water quality and water temperature. Especially the change in water temperature, the extreme sudden change in water temperature that goldfish can withstand is 4 degrees Celsius. Exceeding this limit will inevitably cause illness and even death. Therefore, when changing water and changing the tank for goldfish, pay attention to the change in the new and old water temperatures. In addition, sudden changes in water hardness and pH will also affect the goldfish's biological protective film, causing the goldfish to become sick. The correct approach is: before changing the water, air the new water for 3 days to make the water temperature within 1 degree Celsius of the old water, and volatilize the chlorine in the water. Keep the amount of water changed below 1/2, and slowly inject new water. In an emergency, you can add a water stabilizer to the new water to quickly remove harmful substances in the water. Add boiling water and use a thermometer to measure the water temperature until it rises to a temperature close to that of the old water. But it is not suitable for precious species. If the light is too weak or too strong for a long time, it will also affect the body color and growth of goldfish. The dissolved oxygen content in the water is also a key factor. If the dissolved oxygen content is too low, it will cause "floating head" at the least, and suffocation and death at the worst. The easiest way to solve the dissolved oxygen content is to use a special air pump for aquariums. And choose the appropriate power according to the water volume. In addition, the use of external circulation filtration can also increase the oxygen content in the water. For harmful substances produced by goldfish metabolites, water changes and the addition of nitrifying bacteria can be used to solve them. 2. Physical damage: In the process of moving goldfish, it is easy to cause damage to the goldfish's body surface, and in severe cases, it may cause the goldfish's internal organs to rupture and cause death. In addition, if there are sharp ornaments in the aquarium, such as coral stones, plastic water plants, etc., bubbles may be punctured and pearl scales may be scraped off. Even the danger of physical damage may occur due to excessive suction of the water pump or too fast water flow. Therefore, it is recommended to use a water scoop to scoop the goldfish when moving it. The action should be light and fast, otherwise it will be damaged due to the goldfish's struggle. In addition, when transporting goldfish, the best transportation route and means of transportation should be selected to shorten the transportation time and bumps as much as possible. The equipment and ornaments in the aquarium should have a smooth surface or soft material. The water inlet of the water pump can be equipped with biochemical filter cotton (commonly known as "water fairy"). The water inlet of the filter is equipped with a bend pipe to reduce the impact of small water flow. 3. Bacterial infection: Goldfish live in water. Since the space of water is limited and the water is still, it is very easy to breed bacteria. Goldfish purchased from different places may also bring viruses. In addition, rotten food can also cause enteritis in goldfish. Diseases caused by bacterial infection should be observed frequently, treated early, and isolated early. Sick fish that are terminally ill should be eliminated decisively. 1. Common treatment methods for fish diseases at home mainly include: medicated bath, medicated bait, and mechanical correction. Medicated bath: Usually a certain concentration of liquid medicine is used to soak the fish body. For fish diseases caused by bacterial infection, a low-concentration spraying method is often used throughout the tank. The more commonly used drugs include: salt, furazolidone, potassium permanganate, methylene blue, red medicine, etc. The above drugs are less toxic and suitable for home use. Medicated bait: Chinese and Western medicines, such as oxytetracycline and allicin, are mixed into feed to feed sick fish. Finished products can be purchased from the market. Mechanical correction: For goldfish swim bladder diseases, foam plastics can be tied to the fins to help the goldfish swim. 2. Observe whether there are parasites on the surface of the goldfish, white hair, white spots, bleeding, ulceration. The judgment of goldfish's body surface diseases is relatively complicated, and the dosage of the drugs is complicated. There is no need to learn anything special for home fish farming. You only need to follow the following "local methods" for prevention and treatment: Drug name Concentration Treatment salt 3/1000 Treatment. 1/1000 Prevention. Surface bacterial diseases Add a match head-sized amount of furazolidone powder to 40 kg of water and dissolve it with a small amount of white wine. Surface bacterial diseases and enteritis Take out the fish with potassium permanganate, add old water until the water turns cherry red, and soak for half a day before changing the water in the entire tank. Clean the tank and disinfect Methylene blue Add water until the water turns sea blue Surface bacterial diseases Apply red medicine directly to the affected area and keep it away from water for 10 seconds Ulceration In addition to the above traditional medicines, you can also purchase commercially available special medicines under the guidance of experts and use them strictly according to the instructions. 3. For goldfish that float on their backs for a long time due to swim bladder problems, you can tie a foam plastic of appropriate size at the root of the third fin ray of the dorsal fin to allow the fish to float and swim freely. Hope this helps.

You can use tap water, but you have to open it for more than a week to let the chlorine in the water escape. If you use the tap water that Duan Juye has just released, the fish will die! Just change 1/3 of the water each time, or less. If you don't mind the trouble, you can change a little bit a day. This thing is a little bit of a test, and you can summarize your experience little by little!
