Extended data:
Raising tropical fish requires controlling the water temperature. Generally, many people control the water temperature at 25 degrees, buy suitable heating rods and thermometers, so that they can observe the water temperature and turn on the lights regularly to let the fish work and rest regularly. Generally, five or eight hours a day is enough. Although the fish has no eyelids, it still rests and is quiet in the dark.
However, after turning on the light, it will become very active. When raising, you should pay attention to changing the water frequently, but you must be careful not to change it all. Beginners usually make this mistake, which is a big mistake. If the fish adapt to the environment in the aquarium, try not to change it, because tropical fish will also be acclimatized.
When changing water, it is enough to change it once a week. In the process of changing water, it doesn't need too much, just a quarter, to ensure that the water temperature doesn't change too much, and the filter cotton in the filter tank must be cleaned. If it can't be cleaned, change it. Ceramic rings don't need cleaning. Even if it is dirty, change it part by part.
You don't need to be full when feeding, because the fish can't finish eating, and the food will stay in the water, which will make the water quality worse. In addition, the filtration system must not be shut down, because the filtration system will increase the oxygen in the water. If you turn off the fish in the water, there will be lack of oxygen, and the nitrifying bacteria in the filter pool may die.
