How Long Can A Betta Go Without Food?

Betta fish are definitely some of the most popular and cool looking fish around. They might be a little aggressive and feisty, but that is the exact reason why many people keep them, plus they just look awesome too. That being said, betta fish do need to be taken care of.

After all, when inside of an aquarium, it is not like they can feed themselves. This brings us to the question of how long can a betta go without food? No, we don’t want you to test this out, but people are often worried about going to work, school, or even a short vacation while leaving the fish at home.

So, How Long Can A Betta Go Without Food?

Ok, so most people feed their betta fish once or twice per day, which is totally fine if you don’t overfeed it. Yes, overfeeding is definitely a thing with all fish. They are not that smart and they will eat and eat, more or less until they either sink or pop.

The point is that overfeeding your fish is actually a bigger problem than underfeeding them. Many experts actually recommend taking a day or two per week where you do not feed a betta fish at all. This helps give the digestive tract some time to calm down and regroup.

That being said, we do not recommend taking several days off from feeding your betta fish. However, strictly speaking, betta fish can actually survive without food for up to 2 weeks or 14 days. Now, once again, this is not recommended, as day 14 without food is probably the day the betta fish dies due to malnourishment.

However, do not fret if you miss a day or two of feeding, or even a few days. If your betta fish is well fed on the regular, a couple days of no food here and there will not be the end of it.

If you are going to be away for more than a few days, we would recommend some other options. There are many good automatic fish feeders out there which can be programmed to release a certain amount of food over a certain time period. There are also feeding blocks which are more or less a bulk supply of food that gets released into the water over a certain period of time.


When it comes down to it, a couple days of fasting is not going to kill your betta fish. While they can survive for up to 14 days without food, this is definitely not recommended. Always be sure to feed your betta fish a well-balanced diet with lots of protein, doing so regularly.
