The appropriate amount of bloodworms to feed a Siamese fighting fish at one time is about 3 pieces. Specifically, Siamese fighting fish can eat freeze-dried bloodworms. It is recommended to feed them once every one to two days, with about 3 pieces each time. In addition, Siamese fighting fish can also eat tubifex worms, bloodworms, daphnia, brine shrimp and other foods. Feed them 2 to 3 times a day, with 2 to 3 pellets of fish food each time.
The digestive system of Siamese fighting fish is rather delicate. When feeding, we should follow the principle that "fish won't starve to death, but they can be overfed to death." Avoid overfeeding, which may lead to diseases such as ascites, swim bladder disorder and enteritis. Therefore, it is recommended to feed them once every one to two days, with 5 to 8 pellets of fish food each time (for giant bettas, you can double the amount).
To keep the water quality clean, the remaining food should be removed promptly after feeding to prevent water pollution and the outbreak of bacterial diseases. Moreover, the breeding environment of Siamese fighting fish is also very important. The water quality should be kept slightly acidic, and the water temperature should be stable between 25 and 28 degrees Celsius.
