How Long Can Betta Fish Go Without Food?

Betta fish are hardy fighters that need care just like any other pet. If you’re on your way out the door for extended time away, you might be scratching your head on what to do with the fish. Betta fish have small stomachs and should be fed small amounts of food a few times a day. However, they are able to go without food for a short period of time if necessary. It is generally recommended to not let betta fish go without food for more than a week (10-14 days technically), as they can become weak and stressed. Maintain a feeding schedule and not overfeed betta fish to ensure their health and well-being. Although this is hopefully long enough to cover your vacation or extended trip away from them, it might be best to have a few other options on the table such as…


Feeding Your Fish from Afar: 3 Fantastic Methods

Now that you know your betta’s potential for survival, let’s get into the nitty-gritty of keeping them fed when you’re away. I’ve got three fin-tastic methods for you:

Ask Someone to Watch Them

Since bettas typically live alone, their tanks are likely small enough to transport if needed. If that’s not the route you’re looking to take, you can always ask a trusted neighbor or friend to check in on them once or twice while away. If you don’t have anyone that can look after your fish, it might be worth looking into an automatic fish feeder.

Get An Automatic Fish Feeder

There are tons of options for automatic fish feeders and they are very inexpensive devices that typically cost about $20. We like the Fishnosh automatic fish feeder because it’s good for most tank sizes or even a pond. It is completely programmable and can run up to 9 times per day. Includes measuring indicators, manual feeding, and it works with any dried fish food. Can be clipped on, or glued to the top of a tank.

The Feeding Block: Slow and Steady Wins the Race

If you can’t get someone to watch over your fish and prefer a more natural approach, the feeding block might be for you. It gradually releases food for your betta over time, avoiding overeating. But be cautious – leaving it too long can lead to water contamination and ammonia buildup.

Preparing Your Tank for Your Great Escape

Before you embark on your adventure, remember that preparation is key. Here’s a checklist to ensure your betta’s kingdom is shipshape:

Keep Conditions OptimalClean the tank, gravel, and trim plants. Test the water’s pH level to ensure it’s in the safe zone (6.8 – 7.5). Check the filtration system, air pump, and heater. A healthy tank means a happy fish.

Check Your Tank Heater

Bettas adore tropical waters, so set your heater between 75-80°F (24-27°C). Place the tank away from direct sunlight or heating vents. Keep it draft-free and cozy.

Set a Timer for Your Tank Lights

Maintain a daily routine for your fish by setting a timer for 8-10 hours of light each day. Your betta will thank you for sticking to their schedule.

Lid On, Fins In

Bettas are acrobatic little swimmers, and they might attempt daring escapes when you’re not looking. Keep them safe and sound by securing a lid on the tank.

Factors Impacting How Long Can They Bettas Can Survive Without You

Tank Size

Smaller fish tanks are more easily overwhelmed with the toxicity of fish waste. The larger the tank, the longer they can survive without care. The smaller the tank, the more dirty the water will become over time. This can easily negatively affect the betta while you’re away, and can add stress on them, shortening their lifespan.

Filtered Vs. Unfiltered Tank Setups

Another factor to consider before leaving your betta for an extended period of time is whether the fish tank is filtered or not. Unfiltered tanks typically means that their water is changed frequently. If they’re left to sit in an unfiltered tank, you should weigh how often their water changes are against how long you expect to be away for. If it’s significantly longer than what they are used to, it might be a good idea to ask for help.

Tanks that have filters running on them are typically better off than unfiltered tanks. Again, take a look at how often you change their water and weigh that against their needs. It might be a good idea to change your filter a few days before you leave for your trip so that you’re giving them the best filtration possible before you go.

Improve The Overall Water Conditions

Speaking of changing filters, it’s a good time to do all of your regular maintenance before you go. This might mean doing a partial water change, running a test on the pH levels, and giving the tank the usual maintenance you’d do albeit a little bit early. It’s good to not shock your betta, so be sure to take into account the usual maintenance schedule you’ve got, and use your best judgement.

Should I use an automatic fish feeder?

Betta fish can be a bit particular about their meals, especially if they’re used to specific types of food. Automatic feeders can work, but here’s how to make sure it’s a success:

  1. Test the Waters: Try out the automatic feeder well before your trip to ensure it’s working smoothly.
  2. Ten-Day Feast: Let your betta enjoy the automatic feeder’s meals for around ten days before your travels. This helps them get accustomed to the new feeding routine. This is also a great time to tweak placement, and to make sure the equipment is working as expected.

How long can a sick betta fish go without food?

When dealing with a sick betta fish, their ability to go without food can be impacted by their specific health condition. Sick bettas might not have much of an appetite due to their condition. They could go without food for a few days. However, it’s crucial to keep a close watch on their behavior and health. If their lack of eating continues or worsens, it’s time to reach out to a fish-savvy vet.

Remember, nutrition plays a key role in their recovery process. If your betta is under the weather, providing them with proper care and creating the best possible environment is essential.
