How Long Can Bettas Go Without Food?

How Long Can Bettas Go Without Food? There has been talk of starvation lately and I haven’t seen much information on the Internet other than that Bettas can live only three days without food. As a matter of fact some stores are selling betta foods for exactly 1-3 days supply which is incorrect since it not what they need to live but rather how long until they die if they don’t eat at all in the given time.

1. How Long Can Bettas Go Without Food?

A betta fish can live up to 4 days without food and this is the amount of time it would take them to die from lack of energy. They are very resilient, but at the same time they need to eat almost constantly. One day is usually more than enough for their metabolism (digestion) if you feed once a day. Of course they could go for two or three days without food, but there will be consequences later on.

2. Not Feeding Your Betta For A Day Or Two Can Be Healthy

If you decide not to feed your Bettas don’t feel bad about it; Betta fish have been naturally evolved in such a way that even though they can survive longer with no food they still need to eat. This is specifically what makes them part of the biological term known as r-selection and not K-selection species.

3. Living Conditions Determine How Long Betta Fish Can Go Without Food

Bettas live in a tropical environment where the temperature ranges from 23°C – 28°C (73°F -82°F). They are also native to an area with low oxygen levels and this means that they have developed strategies to deal with scarce or limited resources in the water. The same principle applies when it comes to food for your betta fish; if you feed them once every day they will be able to go without food for 1 full day, but if you starve them then they can only survive another 1-2 days.

4. Things to Avoid with Betta Fish Feeding

It’s important that you don’t feed your betta fish too much and even if they have just been fed for a few hours you can safely give them some more food as long as it won’t fill their stomach up again within 2-3 hours. The reason why we shouldn’t overfeed is because this causes stress on the digestive system which will lead to constipation or swim bladder disorders. Also, when the time comes that you need to treat them for any disease, such as parasites, then one of your main enemies will be overeating so let your betta go hungry before hand so they get sick easier.

5. Why is Ammonia Dangerous for Betta Fish?

This is a very common and dangerous situation for bettas since they are inhabitants to low pH levels of 6.3 or even lower at times. Also, ammonia isn’t the only problem when it comes to high pH level in water; waste products such as fecal matter and uneaten food will cause an increase in ammonia concentration which will then lead to stressing your fish out even more. To be safe rather than sorry you should remove any solid wastes from your aquarium every day if there is any ammonia present in the water (even if their gills look healthy). The proper way we like to do this and make sure that all solids have been removed from the water is by using aquatic plant systems that can be kept in the aquarium for almost a month before they need to be replaced.

6. Conclusion

Make sure that you are placing your betta fish into an environment where there will be enough oxygen and food for them to thrive in (especially if they are growing). They only have so much reserve energy inside of their bodies since they evolved with very little or no food at all, but this doesn’t mean that it’s healthy for them. Always make sure that you have plenty alternative feeding methods available when you feed your betta fish; this way their consumption won’t go down and you are saving yourself from potential health issues later on. Good luck!
