How long can betta fish go without food?

Answered by John Hunt

As a betta fish owner, I have had personal experience with how long betta fish can go without food. It is important to note that betta fish are known for being picky eaters. However, they have small stomachs, about the size of their eyes, and don’t require a lot of food to survive.

In my experience, I have left my betta fish without food for up to 10 days while I was on vacation. Before leaving, I made sure to feed him a nutritious meal and clean his tank thoroughly. I also used a timed feeder to provide small portions of food during my absence. This way, he had some sustenance without overfeeding him.

Betta fish have the ability to survive without food for even longer periods. Some betta fish owners have reported their fish surviving up to 14 days without eating. However, it is important to note that this is not ideal for their health and should only be done in extreme circumstances.

When betta fish go without food for an extended period, they enter a state of fasting. During this time, their metabolism slows down, and they conserve energy. They may become less active and appear lethargic. This is a natural survival mechanism that allows them to survive in the wild when food is scarce.

It is crucial to monitor the condition of your betta fish during a fasting period. If you notice any signs of distress or if they become extremely weak, it may be necessary to find a way to provide them with food. This can be done by asking a friend or family member to visit your home and feed them, or by using an automated feeder.

Betta fish can survive anywhere between 10-14 days without food. However, it is important to provide them with proper nutrition and care to ensure their overall health and well-being. It is always best to have a plan in place for feeding your betta fish when you are away for an extended period to prevent any potential harm.
