Overfed Betta Fish

Sharing is caring!

Are you suspecting that your betta fish is overfed? I know it can be hard to resist those big, begging eyes every time you walk by the fish tank, but it’s important to ensure your betta isn’t overfed.

When your lovely pal is overfed, he can end up with a bloated stomach, which can be uncomfortable and even dangerous.

Also, it can seem like your betta is swimming less and less and may even be hanging out at the bottom of the tank more than usual. And, of course, there will be uneaten food floating around in the tank.

If you think your betta might be overfed, don’t worry! You can do some simple things to help get your fish back on track.

In this article, I’ll share with you some tips on how to tell if your betta is overfed and what you can do to help.

How Do I Know If I’ve Overfed My Betta Fish?

There are a few telltale signs that your betta fish is overfed:

  • Bloated Stomach: A bloated stomach is one of the most obvious signs that your betta is overfed. If its belly looks swollen or distended, it indicates he’s been overeating.
  • Less Activity: If your betta is swimming less, hanging out at the bottom of the tank more, or seeming generally lethargic, it could be because it’s slightly uncomfortable from overeating.
  • Uneaten Food: Of course, if your tank is full of floating uneaten food in tank water or floating fish pellets in water, that’s a pretty good sign that your betta fish is being overfed
  • Swimming Weirdly: If your betta fish is swimming weirdly, it could signify a swim bladder disorder. It might swim awkwardly or wobbly because its bloated stomach makes it difficult to move around normally.
  • Diarrhea or Constipation: Bloating can also cause diarrhea or constipation in fish. If your betta has an unusually loose or watery stool, it’s a sign that something is wrong.
  • Cloudy water: If the water in your tank starts looking cloudy, it’s a sign that there’s too much food in the cool water, and it’s starting to spoil

How Do I Avoid Overfeeding My Betta?

The best way to avoid overfeeding your betta fish is to stick to a regular feeding schedule. I recommend feeding your betta twice or three times a day.

Once you feel like your betta is getting the hang of things, you can experiment with different feeding schedules to see what works best for your fish.

Also, avoid any type of pellets or flakes that expand in fresh water. These can cause your betta’s stomach to bloat and can be difficult for them to digest. Instead, stick to a high-quality pellet or flake food designed specifically for bettas.

Finally, ensure you’re using food that doesn’t contain fillers or artificial ingredients. Believe me. These toxins can build up in your fish’s system and cause health problems down the road.

I Already Overfed My Betta! What Should I Do Now?

Whether you overfed your betta by accident or you just realize that your fish has been overfed for a while, don’t worry! You can do some simple things to help get your betta back on track.

First, cut back on the amount of food you’re giving this labyrinth fish. If you’ve been feeding three times a day, cut back to twice daily. And if you’ve been feeding twice a day, cut back to once a day. Just make sure you’re not skipping any meals!

Next, do a water change. I recommend doing a 50% regular water change at least once weekly. This will help to remove any uneaten food or waste from the tank and eliminate poor water quality.

Plus, keep an eye on your betta’s stool. If it starts to look loose or watery, it’s a sign that your fish still has trouble digesting its food. In this case, you may need to cut back on the amount of food even further.

Finally, observe if they have any signs of constipation. Some signs of constipation in fish include lethargy, loss of appetite, lack of defecation, and a distended abdomen. Sometimes constipation might even develop into swim bladder disorder in bettas due to the poor water conditions, which can be fatal.

How Does Constipation Turn into Swim Bladder Disease?

Constipation in fish can sometimes develop into swim bladder disease. Swim bladder disease is a condition that affects the swim bladder, an internal organ that helps fish float and maintains their balance in aquarium water.

When a fish’s food doesn’t get digested properly, it can start to ferment in the gut. This fermentation process produces gas, which can build up in the swim bladder. This can cause the swim bladder to swell and pressure other organs, which can be very painful for the fish.

How To Cure Constipation/Bloat/Swim Bladder Disorder in Betta Fish?

To help prevent constipation and swim bladder disease, ensure you’re feeding your betta high-fiber foods. These foods contain indigestible plant material that helps to move food through the digestive system and prevents constipation.

If your betta fish is constipated, you can do a few things to help ease their discomfort. First, try feeding them high-fiber food. This will help to move food clogs through their digestive system.

Another alternative is to feed them a one-week course of erythromycin or metronidazole fish antibiotics twice a day. This will cure any bacterial infection or fish fungus and provide fast alleviation from symptoms of swim bladder disease.

If your betta does not respond to these treatments, you can quarantine them and give them a laxative. The most common type is sorbitol which they take orally once daily for up to three days in a row.

In my opinion, the most effective approach is to withhold food until they start to recover. After leaving them for three days without food, you may offer your betta some daphnia. Daphnia is a natural laxative that may help your betta clean his intestines.

If it does not enjoy daphnia, offer them 1/4 of a deshelled pea instead. To do this, boil it first. Once the pea is cooked and cooled, remove its skin. Then, cut 1/4 of the cooked, deshelled peas into tiny bite-size pieces and offer them to your betta.

After 10 days, you can give your betta an Epsom salt bath if it does not show any progress. Some people even prefer to do this as soon as they notice their fish has swim bladder disorder symptoms.

To do this, add 1 tablespoon of salt to every water gallon. This should cure your tropical fish within a few days.

Can Overfeeding Lead To Death in Betta Fish?

Overfeeding can end up killing your betta fish if not corrected in time. When a betta’s stomach is full, digestive juices start to digest the food inside. If this continues for too long, the food will start to rot and produce toxins that can poison your fish.

Aside from that, overfeeding can deteriorate your water level quality because of all the uneaten food and waste. Moreover, water oxygen levels will start to decrease as the decomposing food takes up more space in the unclean water tank.

All of these factors can lead to your betta getting sick and eventually dying. So, it’s important to be mindful of how much you’re feeding your fish and clean up any uneaten food immediately.

What To Feed My Betta Fish?

Overfed Betta Fish

Betta fish are carnivorous. In this fish’s native habitat, they primarily feed on blood worms, mosquito larvae, brine shrimp, daphnia, and small fish.

In captivity, you can feed your betta various foods such as blood worms, wingless fruit flies, Mysis shrimp, brine shrimp, daphnia, and krill. You can also offer them pellets or flakes, but make sure they’re high-quality and contain all the nutrients your betta needs.

When it comes to pellets and flakes, it’s best to soak them in clean water for 5-10 minutes before feeding them to your fish. This will help soften the food and make it easier for your betta to digest.

A betta fish can live for up to two weeks without food. However, this is not ideal as your fish will start to lose weight, and their health will deteriorate over time.

How Do I Know If I Overfed My Betta Fish?
