Purchase a dry cell air pump or rent an oxygen cylinder for oxygenation to prevent hypoxia caused by sudden changes in water quality. Or use a board to divide a space in the aquarium and slowly pour in a small amount of boiling water, but be careful not to hurt the fish and pay attention to changes in water temperature.
You can also put hot water in a Coke bottle or hot water bottle and then put it in the tank, but remember to always pay attention to changes in water temperature, use a comforter or heater; -insulating panel.

The temperature of the water where tropical fish live is generally between 20 and 30°C. However, different types of tropical fish also have different water temperature requirements. Fish species such as guppies, red swordfish and black marlies can tolerate water temperatures of around 10°C without dying, while swallowtails, tiger fish and other species will die when the water temperature is below 18°C.
Most tropical fish are extremely sensitive to water temperature. If the water temperature changes by ±2°C, they will catch a cold. If the water temperature fluctuates unsteadily for a long time, the fishoThey will suffer from various ailments. diseases. Therefore, the water temperature should be kept as constant as possible. The water temperature should not be too high. Fungi in the water will multiply too quickly and affect water quality.
