Why your Betta fish is spitting out

We will see in this blog what the main reasons are for your betta fish to be spitting food right after feeding and what can be done. Some people relate this problem to the size of the food or digestive problems, but let’s see in detail.

Size of the food

The most typical cause for your betta spitting out food is that it is too large. Your betta’s stomach is around the size of its eyeball, and some pellets are considerably larger. In many circumstances, your betta will spit food out since he can’t consume it. However, this does not imply that he is not eating. He may occasionally take little pieces of food.

What really happens is that when food falls into your pet’s tank, he will grab it and try to consume it. The dry food begins to expand as soon as it reaches your betta’s mouth. Your pet realises he can’t swallow that enormous chunk of food and spits it out.

While it appears that he is spitting out the meal, he is actually breaking it up into little fragments and making the main component more edible. While this is the most prevalent explanation, it is far from the only one. Here are a few of the most prevalent causes.

Digestive Problems

Digestive problems might be another reason for any betta fish spitting out food. Digestive issues are rather frequent in bettas, therefore it is conceivable that your betta is experiencing the same. You should not be concerned about this.

Constipation is the most common digestive problem. Based on its faeces routines, you may simply determine whether your fish has constipation. If it hasn’t been defecating on a regular basis, it is most likely constipated. To remedy this, ensure that your betta fasts for two to three days before feeding it daphnia.

If constipation is left untreated in severe situations, it can progress to a more dangerous illness known as swim bladder disease. Constipation causes bloating, which puts undue strain on the betta’s organs, particularly the swim bladder.

This impairs the fish’s ability to balance, swim, and stay upright in the water. Many times, you’ll see your fish attempting to swim upside down or even on his side. When the bloating subsides, the strain on the swim bladder is removed, and he may resume swimming properly.

Even if you feed your betta the greatest fish meals available, too much of a good thing can be harmful to your fish. Many fish species may happily chew on food all day without becoming unwell. Bettas, on the other hand, are extremely susceptible to overfeeding, and even following the manufacturer’s guidelines on many fish food packages can lead to overfeeding.

Some betta fish food packaging suggests giving your betta whatever your pet will eat in two to five minutes. That’s a lot of money for a betta fish! A full-grown adult betta should be fed two to three pellets or three to four bloodworms twice each day.

Feeding Frequency

Feed your betta twice a day, if feasible. Two short meals are preferable to one huge meal for your pet’s digestive system. It’s also critical to have at least one day every week where you don’t feed your betta at all.

Fasting may appear harsh, but it is really beneficial to your pet since it allows waste in your fish’s digestive system to pass through before more food is added to the burden. This helps to reduce constipation and bloating, both of which can cause your fish to spit up food.

Maybe your Betta is too young

If you’ve recently acquired a new betta fish into your house, chances are they’re still in their infancy. Young bettas are typically fed just live food for ease of digestion. Therefore if you’re giving them pellets and flakes, you should change their diet.

Your Betta might have parasites in the stomach

Although it is uncommon, bettas might get parasites in their gut on occasion. These parasites might prevent your betta from eating correctly. Even though he is hungry, he may be unable to swallow food and will instead spit it out.

The likelihood of it being a parasite, on the other hand, is far lower than that of anything less nasty. However, if you suspect your betta is infected with a parasite, you should place him in a quarantine tank. This prevents him from contaminating your aquarium and infecting other fish.

Maybe you betta is distracted

Sometimes your betta is just being picky or foolish. He could not realise what you’re feeding him is food, or if he does, he’s decided he doesn’t want it. Apart from the food being too large, this is the most typical reason for your betta spitting out food.

If you believe this is the case, all you need to do is keep giving him what you have. He might not eat anything at first, but the more hungry he becomes, the more likely he is to consume it. Remember that if your betta does not take food within 10 minutes, you should remove it from the tank.

Other Reasons for betta fish spitting out food

Like humans, fish are extremely sensitive animals to what is happening in their surroundings and may spit out food for a variety of reasons. See a summary of other reasons:

  • They dislike the texture of the food. Flavourless flakes, pellets, and other professionally made foods may be to blame.
  • The portions are very huge. To successfully chew their meal, the betta fish will have to spit it out and consume it again.
  • If another fish steals the betta’s food, the betta may get terrified and avoid eating the food for fear of being harassed by the other fish.
  • If a live food culture, such as brine shrimp or bloodworms, wiggles around in the betta’s mouth, it may become an irritation, causing your betta to spit them out.
  • The meal does not smell nice and is not appealing to the betta fish.

Select good and suitable foods for your betta

Betta fish are carnivores who should only consume meat-based protein. Plant matter and algae will not pique their interest in their diet, and they will normally avoid consuming these sorts of foods. Bettas should be given a commercial food that is made for bettas and contains carnivorous fish nutrients.

Plant materials should be present in trace amounts in commercial betta meals. This may be determined by ensuring that algae and other leaf-based meals are listed towards the end of the ingredients list, implying that there are only minor traces in the actual dish.

Nutritional Analysis of Betta Fish

In terms of nutritional percentages, a decent betta diet will often comprise the following. Betta fish prefer protein-rich diets and are less likely to spit them out. A general assured analysis of betta food should fall within the following guidelines:

Crude protein35%-48%
Crude fat2.0%-6.0%
Crude fibre2.0%-6.0%
Moisturemax. 5%-12%
Ashmax. 3%-15%
Phosphorousmin. 0.3%-0.9%

What Bettas Shouldn’t Eat

Some meals can cause your betta fish to spit them up simply because they do not taste good! Bettas may be finicky when it comes to particular meals, and it is our responsibility to ensure that they are satisfied not only by the flavour of the food, but also by its nutritional value.

Here are some things to avoid feeding your betta and to prevent them from avoiding specific meals:

  • Algae
  • Live plants
  • Omnivore foods
  • Flakes
  • Bottom feeder pellets
  • Goldfish foods

When to Be Concerned About Appetite Loss

When a betta fish isn’t feeling well, he or she will usually refuse to consume things that they used to enjoy. This is seen by your betta fish refusing to eat any sort of food you provide them. This includes living foods such as bloodworms, microworms, and insect larval cultures such as mosquito larvae.

Many different sorts of ailments might induce appetite loss. Your betta may refuse to eat if he or she is suffering from a medical condition such as dropsy or fin rot. Many illnesses will make your betta too unwell to eat properly, resulting in them spitting out their food and then leaving it.


Bettas who appreciate the flavour of their food are less likely to spit it out. As a result, it is critical to supply your betta fish with the healthiest food possible, consisting solely of protein-rich components. If you believe that your betta fish is spitting up its food because it is unwell, it is advisable to treat it with the appropriate medication and observe whether or not its appetite changes after that.
