Can a betta fish go 2 days without food?

Betta fish can survive for short periods without food, but it is not recommended to leave them without food for more than 2 days.

Betta fish have a relatively slow metabolism and can store energy for a few days, but they still require regular feeding to maintain their health. After two days without food, they may start to show signs of malnutrition, such as weight loss, lethargy, and a loss of appetite.

It is important to feed betta fish a balanced diet that includes proteins, vitamins, and minerals. A variety of foods can be offered to betta fish, such as live or frozen foods (such as brine shrimp or bloodworms), freeze-dried foods, and commercially prepared pellet or flake foods.

The amount of food that a betta fish needs will vary depending on its size and age. Generally, adult betta fish should be fed 2-3 times per day, and young betta fish should be fed more frequently.

If you are going to be away for more than 2 days, you can provide your betta fish with a slow-release food block or feeder that will gradually release food into the tank. You can also ask a friend or family member to feed your fish while you are away.
