The breeding of young betta fish requires attention to several aspects, such as keeping them in isolation, controlling the water temperature, maintaining water quality, feeding them with appropriate food, and avoiding the overuse of medications.
Newly born betta fry need to be isolated from the big fish tank and placed in a quiet and stable environment to avoid being attacked by larger fish. The water temperature should be kept between 26 and 28 degrees Celsius, and large fluctuations in water temperature should be avoided. The quality of water directly affects the health of betta fish, so it's necessary to change the water regularly to keep it fresh and clean. Feed them with appropriate food, like small plankton or special betta fry food, twice a day, and the amount of each feeding should be just enough for the fry to finish within 5 to 10 minutes. Besides, avoid overusing medications, and consult professionals for advice before using any medications.
When it comes to food selection, you can use egg yolks, water fleas, and small pellet food. Egg yolks can be mashed and dissolved before feeding them to the fry, while water fleas and small pellet food can be used when the fry grow a bit bigger. To ensure the safety of the fry, you can put a net cover on the aquatic plant bucket to prevent attacks from natural enemies like dragonfly larvae.
In terms of the breeding environment, you can use small aquariums or isolation boxes, and install filters or water purifiers to improve water quality. Keeping the environment quiet and stable is helpful for the healthy growth of young betta fish.
