What kind of cold water fish should be kept in a fish tank?
Blood parrot
Blood parrot is a kind of yin and yang fish. Like the so-called liger and mule, it has no ability to reproduce the next generation. ability. Don't get excited if you see it laying eggs, as there is absolutely no chance of them hatching. This is a new fish produced in Taiwan by mating the red manta ray and the purple firemouth introduced from South America. This kind of breeding technology has not been completely learned abroad so far. Only Taiwan can cultivate such fish species. Due to its flame-like appearance, bright red color, and elegant posture, it quickly became the number one brand of feng shui fish in Taiwan!
Its average lifespan is about seven years and it can grow to 20 cm. about. The biggest disadvantage is that it is afraid of cold, so be sure to install a thermostat in the fish tank to maintain the temperature at 28-30 degrees Celsius.
Goldfish
Gold is an ornamental fish species that was continuously improved from carp during the Song Dynasty in China. It is also called the national treasure fish. Today, there are many types of goldfish, and it is difficult to identify their species. There are more than a hundred species on display at the Goldfish Museum in Hong Kong's Ocean Park.
The more popular varieties include blister eyes, red peonies, black pearls, teapots, etc. Goldfish symbolizes wealth, happiness and longevity. Very popular among fish lovers. The biggest problem is that they are prone to fish scale diseases, which requires special attention.
Koi fish
Koi fish have been raised in China for longer than goldfish, but as the main ornamental fish and even Feng Shui fish, koi fish have been developed in Japan. Koi has always been regarded as a spiritual fish that can bring prosperity to the family. However, due to limited breeding space, there are not many families raising Feng Shui fish like koi, mainly enterprises and institutions.
Red Dragon and Silver Belt
The red dragon is the best fish in Feng Shui. In the Chinese society, this fish native to Indonesia is believed to have the power to ward off disasters and relieve disasters. The advantage of seeking good fortune and avoiding misfortune is that it can even physically take the place of the owner in disaster, so that the owner can avoid bad luck.
In the early days of Indonesia, the red dragon was considered a food fish because of its large number. Later, it became famous as a Feng Shui fish, but overfishing was very serious because of this. Now it is regarded as a protected animal and public trading and breeding are prohibited. At present, Singapore and Indonesia have cooperated to develop artificial breeding and breeding methods, so larvae can be purchased at high prices under listed conditions.

1. Filtration:
Use the filtration system to cultivate nitrifying bacteria to purify water quality. The filter materials generally choose filter cotton and glass rings. The filter cotton should be cleaned frequently and replaced after one month of use. Filter cotton is not expensive, only 2 yuan for a large piece.
2. Oxygen supply
There is nothing to say about this, it is just to add oxygen to the fish tank. Depending on the actual situation, you can choose an ultra-quiet one, such as the Japanese Yingko Octopus pump or the German EHEIM pump.
3. Heating rod
Whether it is goldfish or tropical fish, there should be a heating rod, which is used to maintain constant temperature. Because the temperature difference is too large, the fish will suffer from white spot disease. The power of the heating rod is selected according to the size of the fish tank.
4. Feeding
Don’t feed too much. Feed once a day at a fixed time and finish it within 3 minutes each time. It’s better to buy fish food as much as possible, but it doesn’t cost much. I bought 2 pounds of artificial feed for 100 yuan. I raised 20 tropical fish at home, and I only fed them about 1 pound in half a year.
5. Change the water
The tap water must be dried for 24-48 hours before the water can be changed for the fish. When changing the water, be sure to pay attention to the temperature. The water change cycle is generally from 3 days to once a week, and the amount of water changed each time should not exceed half of the water in the tank. Change it no more than twice a week.
