What are the precautions for raising fish in a fish tank? How to raise fish well

Fish tank fish should first pay attention to feeding, according to the type of fish, choose the appropriate feed, feed three times a day. Secondly, we should pay attention to changing water, so as to keep the water clean and hygienic, usually once a week, filtration can also be changed half a month. At the same time, attention should be paid to temperature control, the temperature should be appropriate, so that fish can grow healthily. Finally, we should pay attention to oxygenation, and insufficient oxygen will also be harmful to the health of fish.

1. feeding

fish in fish tanks should first pay attention to feeding. Different fish have different feeding habits. Herbivorous fish like plant feed, while carnivorous fish use fish and shrimp as food, so they should choose the right food to feed. Also pay attention to the feeding time, usually between 9 am and 4 pm, when the temperature is suitable and the fish are more appetizing.

In order to keep the water in the fish tank clean, we must change the water regularly. The cycle of changing water is not fixed, which depends on the speed of deterioration of water quality. If the speed of deterioration is fast, it is necessary to change water more frequently, once a week. If the speed of deterioration is slow, it can be changed once a half month, about a quarter each time.

3. Temperature-controlled

fish, as poikilothermic animals, have limited adaptability to temperature. When the temperature is high, they are more energetic and appetizing, while low temperature makes them depressed. Therefore, in winter, we must pay attention to temperature control, if it is tropical fish, at any time to ensure that the water temperature is above 20 degrees Celsius.

4. The oxygen content in the oxygenated

fish tank is particularly important for the health of fish. It is better to prepare an oxygen pump and oxygenate it throughout the day, so as to avoid the occurrence of hypoxia and other conditions. Oxygenation not only helps to breathe, but also maintains water quality better, and is also helpful to establish a nitrification system.
