Crowding Stress

If your betta fish is stressed, it may refuse to eat even if the conditions in its tank are favorable. Consider adding plants or decorations to buffer them from any aggression or stress caused by other fish species in the fish tank.


If your betta fish has contracted a swim bladder disease or infection, it may be unable to eat due to its physical or mental pain. Common signs of illness include lethargy, lack of appetite, discoloration, and scale loss.


While many owners think overfeeding their Betta benefits their health, this can cause more harm than good. If you’ve been feeding them too often, your picky eater fish will become full and may feel like eating less!

It is important to remember that when a Betta does not eat, his health will decline, and he may eventually die.

What to Do If My Betta Fish Isn’t Eating?

Bettas are a popular type of fish, but they can be hard to care for if you’re still trying to figure out what to do.

Why My Betta Fish Is Not Eating Pellets?

Many Betta owners notice that their fish refuses to eat pellets, but there can be several reasons for this.

  • The first and most common reason is that your Betta may not recognize the pellets as food. Bettas are typically used to eating live or frozen fish food, so it may take some time for them to adjust to a different diet.
  • Another reason is that the pellets may need to be bigger or simpler for your fish to swallow. Try breaking them into smaller pieces, or switch to a different pellet specifically designed for Bettas.
  • Lastly, it could be due to overfeeding. If you’ve been giving your Betta too much food, it won’t feel hungry and may not be interested in eating the pellets. Try cutting back on the daily food to see if that helps.

Understanding why your Betta isn’t eating pellets can help you adjust their diet and improve your health. With patience, you should soon see your Betta eating pellets with no problem!

How to Get My Betta Fish to Eat?

If your Betta fish is not eating, there are several things you can do to encourage them to start eating again.

First and foremost, ensure the water temperature in their tank is between 74-79 degrees Fahrenheit – any colder than this, and they won’t be able to digest food properly.

Second, if you’ve been feeding them the same food for a while, try mixing it up with different freeze-dried or frozen foods to make it more interesting.

Third, you can feed your Betta in a different location than usual, near the tank’s surface or in a corner, and this can help to trigger their instinct to forage for food.

Finally, you can introduce some live plants into the tank to create hiding places for your Betta. This will provide them with a sense of security and make them feel.

Why Is My Betta Fish Not Eating or Moving?

Why Is My Betta Fish Not Swimming or Eating? If your Betta fish is not moving, eating, or swimming, it could be due to various reasons. The most common causes include the following:

  • Stress – Stress can occur when Bettas are placed in overcrowded tanks, lack hiding spots, and have poor water quality.
  • Illness – Common illnesses like dropsy, fin rot, and swim bladder disorder can prevent your Betta from eating or swimming.
  • Old Age – As Bettas age, they become less active and may not eat as much as they used to.

If you suspect that any of these factors might be causing your Betta’s lack of movement or appetite, it’s essential to take action.

To keep your pet betta fish healthy and happy, regularly check the water conditions in its aquarium. Have a test kit or strips on hand at all times – you’ll be glad you did if they stop eating!

Why Is My New Betta Fish Hiding and Not Eating?

Why is my betta fish not eating and hiding? This can signify stress or illness and should not be overlooked. A common cause of hiding and refusing to eat is the tank size.

Bettas are solitary tropical fish, so they need plenty of space to feel comfortable in their environment. If your tank is too small, it can cause them to feel anxious, which will lead to hiding and a decreased appetite.

Another possible cause of hiding and not eating could be the water parameters in your tank. Check the pH and temperature levels regularly, as Bettas prefer a neutral pH between 6.8-7.2 and temperatures between 74-79 degrees Fahrenheit.

Frozen foods like krill, Mysis shrimp, and daphnia should also be included in your Betta’s diet.

In addition, to live brine shrimp, mosquito larvae, and frozen foods, high-quality Betta pellets should also be offered for a balanced diet.

The ideal pellet should include omega-3 fatty acids and other essential vitamins and minerals for optimal health and vitality.

Be sure to choose a bullet designed explicitly for Bettas.
