In the early stage after hatching, young betta fish mainly rely on the yolk sac for nutrition and don't need to be fed additionally. During the first three days after hatching, the young fish will absorb the nutrients in the yolk sac by themselves, so there's no need to feed them. Starting from the fourth day after hatching, the young fish can begin to eat. At this time, microscopic organisms such as water fleas, rotifers, and brine shrimp can be used as food, which are easier for the young fish to swallow. As the young fish grow, the proportion of artificial feed can be gradually reduced while increasing the amount of bait with higher nutritional value like brine shrimp.

During the feeding process, the following points need to be noted:
Water Quality Management: Keep the water clean, change the water regularly, pay attention to changes in water temperature, and avoid large differences in water temperature.
Feeding Frequency: Adopt a feeding method of small amounts but more meals. Feed them 2 to 4 times a day to ensure that the young fish have enough nutrition.
Food Selection: Choose food suitable for young fish, such as brine shrimp and water fleas. These foods are rich in nutrients and easy for young fish to swallow.
Through reasonable feeding and management, the healthy growth of young betta fish can be effectively promoted.
