Betta fish is fierce by nature and eats miscellaneous food. It can be fed with synthetic feed, plankton such as bumper worms, silk earthworms and water fleas, or larvae of insects such as wigglers. This fish also eats algae such as aquatic plants. Feeding live food is beneficial to the hair color of fish and makes the surface color of betta fish more gorgeous, but live food may carry germs, so it should be sterilized before feeding.

Synthetic diet is rich and balanced in nutrition, which is beneficial to the growth and development of this fish. However, we should pay attention to reasonable collocation, and don't let the recipe of this fish be too single. The best feeding amount is that the fish can be eaten within 5 minutes, once a day.

Fresh live food will promote the growth and development of betta fish. Live food mainly includes plankton or insect larvae such as water fleas, silk earthworms, bumper shrimps, wigglers, red worms, etc. Red worms will not only promote their growth, but also promote their hair color. However, live bait is easy to bring germs, so do not use it for a long time. It can be fed with artificial feed, which has balanced nutrition and occasionally can be fed with some small fish and shrimps.

If you want them to grow faster, pay attention to the influence of water temperature and water quality. The water temperature should be kept between 24-27 ℃, and the PH of water should be kept between 6.5-7.2. Betta fish like to move on the upper surface of the water, and when eating, they like to stare at the selected food for a period of time before suddenly attacking. Therefore, they don't like food that doesn't move or sinks to the bottom, so they'd better choose floating food.
