As people's quality of life improves, more and more people like to keep pets at home, and goldfish has become the first choice for most people because of its small size. So what will happen to goldfish when they encounter high temperatures? Do goldfish need to be heated during the winter? The following editor will explain them one by one, hoping to help you.

Is it normal for goldfish to have white spots?

White spot disease, also known as Ichthyophthirius punctatus, is a common disease prevalent in freshwater fish. The pathogen is Ichthyophthirius punctatus, which parasitizes the skin, fins, and gills of fish. The body of the worm is densely covered with short and uniform cilia, and the cysts are small white dots that can be seen with the naked eye.

What to do if goldfish has white spots

The safe treatment method is the "old three things", change the water, increase the temperature and add salt. Ichthyophthirius molitor cannot tolerate high temperatures. Generally, the fish will stop growing and reproducing in water around 25℃. When the water temperature rises to 28℃ to 30℃, the fish will detach from the body and die. Therefore, when treating, stop feeding first, then use a heating rod to increase the temperature. The heating process should be slow, and do not adjust the temperature to 30 at once. Then add salt. The amount of salt added is 5 grams per liter of water, and change one-third of the water every day.

Other methods use yellow powder or methylene blue, which are milder. There are also white spot removers, which are effective quickly. However, they contain high levels of harmful ingredients, so they are not recommended.

How to raise goldfish

1. To raise goldfish, the first thing is to keep the water quality stable so that they are not prone to disease. Goldfish like what we usually call old water, which is rich in plankton, but at the same time the water is clear and transparent, and the color is light green. Goldfish raised in old water will have very bright color, increase their daily food intake, and have a strong physique and are not prone to disease.

2. Although goldfish do not have very strict requirements on water quality, excessively high ammonia nitrogen levels in the water can cause chronic damage to goldfish. Poor water quality is very detrimental to their growth, so it is most important to keep the water clean and stable. The second is to keep it oxygenated. Goldfish require a lot of oxygen, which can often be solved with a small air pump. The airflow of the air pump should not be too large to avoid hurting the goldfish.

3. Finally, we need to improve the nutrition of goldfish. It is more appropriate to use special fish food with bloodworms and mealworms. We buy some high-quality goldfish special feed and feed it twice a day, once in the morning and once in the afternoon. It is best not to feed at night, because the activity of goldfish at night is obviously less than that during the day. Eating too much can easily cause indigestion, gastroenteritis, or even swim bladder disease.
