The ideal temperature range for Siamese fighting fish is between 24 and 28 degrees Celsius. Within this temperature range, the metabolism of Siamese fighting fish is at its best. They have a hearty appetite, high activity levels, and their colors are vivid, showing their best vitality. Meanwhile, the appropriate water temperature also helps to enhance their immunity and reduce the occurrence of diseases.
If the water temperature drops below 20 degrees Celsius, the metabolism of Siamese fighting fish will slow down. Their appetite will decrease, and their activity levels will weaken. It may even lead to problems such as indigestion and dull colors. In extreme cases, too low a water temperature may cause the Siamese fighting fish to enter a dormant state or even die. On the contrary, when the water temperature is higher than 30 degrees Celsius, it will put stress on the Siamese fighting fish. Their breathing rate will increase, consuming more energy. In severe cases, it may lead to a decline in immunity, making them more vulnerable to infections.
In order to ensure that Siamese fighting fish can live in the best condition, fish keepers need to regulate the water temperature reasonably. You can use a heating rod or cooling equipment to maintain a constant water temperature, especially paying attention to making fine adjustments to the water temperature during seasonal changes. In addition, when changing the water, make sure that the temperature difference between the new water and the old water does not exceed 2 degrees Celsius to avoid causing a stress response in the Siamese fighting fish.
