One of the best aspects of caring for our pet betta fish is feeding them. Fish come right to the surface and engage with us during eating. They are at their most active and really appreciate the attention we lavish on them.
But what if we have to leave our betta fish tank for a while? Will they be okay without food, or are we really putting a healthy betta fish in danger?
Just how long can betta fish go without food? Let’s take a closer look at this important question!
Betta fish also known as Siamese fighting fish are one of the most popular freshwater aquarium fish. With their long, flowing fins and vibrant colors, it’s easy to see why bettas have captured the hearts of fishkeepers worldwide.
However, caring for these tropical beauties does come with some specific requirements One question that often comes up is how many days can a betta fish go without food?
In this article, we’ll take an in-depth look at betta fish fasting and how long they can go without eating. We’ll also provide tips on feeding your betta while traveling or going on vacation to keep them happy and healthy.
How Long Can Bettas Go Without Eating?
The general consensus is that a healthy adult betta fish can go 1 week (7 days) without food before starvation and malnutrition become a serious risk.
However, just because they can survive a week doesn’t mean you should make a habit of leaving them unfed for that long. Bettas ideally should not go more than 3-4 days without a meal.
Here are some general guidelines on betta fasting:
-
1-3 days – Okay for short trips and weekends away. Give an extra feeding before leaving.
-
4-5 days – Maximum recommended time for vacation. Use vacation feeders.
-
5-7 days – Survival period before health risks increase. Have someone feed them if possible.
-
1-2 weeks – High risk of starvation and death. Only in emergencies.
Bettas can use their body fat reserves for energy while fasting. But after 7 days, those reserves will become depleted. Appetite loss, lethargy, weight loss, organ damage, and infections can occur due to malnutrition.
Young, old, or already underweight bettas have less energy reserves and should not be left unfed for more than 2-3 days.
3 Factors That Affect Betta Fasting
While the 1 week guideline is generally true, there are a few key factors that can impact exactly how long an individual betta fish can safely go without food:
1. Tank Size & Quality
Bettas in larger tanks with clean, filtered water can go longer between feedings. Waste builds up faster in smaller unfiltered bowls and tanks. Poor water quality causes stress and illness.
2. Overall Fish Health
A strong, healthy betta with some extra weight on it can safely fast longer than a skinny, sickly fish. Older and younger bettas also cannot go as long without food.
3. Temperature
Warmer tank temperatures speed up a betta’s metabolism, meaning they digest food faster and need to eat more often. Cooler temps can help them conserve energy. Ideal range is 75°F – 80°F.
Knowing your betta fish and providing the best care possible are key to determining fasting time limits. When in doubt, always err on the side of caution and feed more frequently versus leaving them unfed.
Feeding Your Betta on Vacation
Going out of town? You have a few options to keep your betta fed in your absence:
-
Fish Sitter – Hire someone to come give small feedings daily or every other day. Provide detailed instructions.
-
Automatic Feeder – Dispenses pre-set amounts of food 1-2 times per day. Check it’s working before leaving.
-
Vacation Feeders – Slow-release blocks that dissolve over 5-7 days. Attach appropriately sized chunks to the tank.
-
Extra Feeding – Give an extra large last meal before leaving for a 3-4 day trip. They digest it slowly.
-
Fast – For short 1-3 day trips, just let them fast with clean water. Give double meal upon return.
When using any vacation feeding method:
-
Don’t overfeed. This pollutes water and can kill fish.
-

-

Can Betta Fish Survive 5 Days Without Food?
Believe it or not, even 5 days is not likely to harm your betta fish.
We are getting into a longer period where stress levels could rise. Especially if your betta fish has an underlying condition, you weren’t aware of. The lack of food could make a mild sickness worse.
You should get an automatic fish feeder if you are going to be gone for up to five days. It will give the fish food while you are gone. Someone from your neighborhood, workplace, or family can come by and feed the fish at least once a day.
Just make sure to leave feeding instructions if the person taking care of your fish doesn’t usually keep wet pets. Otherwise, they might accidentally overfeed, which results in heavy water pollution. Or, almost as worse, underfeeding.
Or you can even take the entire betta fish tank over to a safe place. One of these tanks is easy to move to a family member’s house because it is usually only 1 to 3 gallons in size.
It’s not likely that your betta fish will die if you don’t feed it for 5 days. When there are so many ways to make sure your pet stays fed while you’re not home, it’s not nice to do that!
