The optimal breeding temperature for Siamese fighting fish is 24-28℃, with slight differences in different species and environmental requirements. The following is a specific explanation:

I. Analysis of the Temperature Range
Chinese Fighting Fish
Ideal Water Temperature: According to highly time-sensitive and authoritative data, the most suitable temperature for Chinese fighting fish is 24-28℃. Within this range, their metabolism is active, their body color is bright, and their immunity is relatively strong.
Tolerance Range: They can adapt to temperatures between 20-30℃ in the short term. However, long-term exposure to low temperatures (<20℃) will lead to slow growth, and high temperatures (>30℃) will increase the respiratory burden.
Other Varieties such as the Halfmoon Betta
The suitable temperature for the Halfmoon betta is slightly lower, at 20-25℃. However, it is necessary to pay attention to distinguishing it from the Chinese fighting fish.
II. Key Points of Water Temperature Control
Seasonal Management:
Winter: A heating rod should be used to maintain a constant temperature and avoid large temperature differences between day and night.
Summer: The fish tank needs to be kept away from light or a fan can be used to cool it down to prevent the water temperature from exceeding 30℃.
Precautions for Changing Water: The temperature difference between the old and new water should be controlled within 2℃ to avoid stress reactions.
III. Equipment and Monitoring
Essential Tools: A heating rod (with a temperature control function) and an accurate thermometer.
Environmental Assistance: Terminalia catappa leaves can be added to improve water quality, and dark-colored bottom sand and aquatic plants (such as moss) can be used to stabilize the ecosystem.
