The amount of food for a Siamese fighting fish per feeding is usually around 5 to 10 pellets. The specific quantity can be adjusted according to the fish's size and eating speed. For juvenile Siamese fighting fish, you can feed 5 to 7 pellets of granular feed at a time, while adult ones can be fed about 10 pellets. Siamese fighting fish don't need to eat a lot. It's okay to forget to feed them once or twice occasionally. However, be careful not to overfeed them, as this may lead to the fish "overeating" to death.

In addition, the general feeding frequency for Siamese fighting fish is once a day. But during the breeding period, the fry and breeding fish need to be fed 3 to 4 times a day. The best feeding time is between 9 a.m. and 11 a.m. At this time, the Siamese fighting fish need to replenish energy after a night of digestion. On rainy or overcast days, due to the low air pressure and the reduced dissolved oxygen in the water, the feeding amount should be appropriately reduced to avoid fish hypoxia.
To ensure the health of Siamese fighting fish, it is recommended to adjust the feeding amount according to their eating speed and changes in body size, and be careful not to overfeed.
