Then, using a sharp knife or scissors, make a small incision just below the fish’s belly and gently squeeze out the excess fluid.

Bloated Betta Vs Dropsy
Bloated Betta Vs Dropsy: What’s the Difference?
Your betta fish may look healthy and happy one day, and then the next you notice that its belly is looking a little bloated. So, what’s going on?
Is this bloating just a normal part of the betta life cycle or could it be something more serious, like dropsy? Here’s a look at the difference between these two conditions so you can better understand what might be going on with your fishy friend.
What is bloating in bettas?
First things first, let’s define bloating. Bloating in bettas refers to when their bellies swell up due to gas build-up or constipation. This swelling can make their scales appear raised, which is why some people mistake it for dropsy (more on that below).
While bloating isn’t usually a serious condition, it can be uncomfortable for your fish and if left untreated, can lead to more serious problems like swim bladder disease.
What causes bloating in bettas?
There are a few different things that can cause bloating in bettas, but the most common culprit is constipation.
This can happen if your fish isn’t getting enough fiber in its diet or if there is something blocking its digestive tract (like undigested food). Other less common causes of bloating include overeating and stress. Bettas are known to gulp air when they feel stressed, which can cause their stomachs to bloat.
In rare cases, an infection or tumor may also cause bloating.

How Do You Reduce Bloating in Fish?
When it comes to reducing bloating in fish, there are a few things you can do. For one, you can soak the fish in brine for about 30 minutes before cooking. This will help to expel some of the air from the fish and reduce bloating.
Another method is to cook the fish whole. This allows the heat to penetrate the fish more evenly and helps to prevent bloating.
Finally, you can try using a skewer or toothpick to make small holes in the flesh of the fish before cooking.
This will allow any trapped air to escape and again, prevent bloating.
Can a Bloated Fish Recover?
Yes, a bloated fish can recover if the cause is not something serious like an infection. The most common cause of bloating in fish is overeating, which isn’t fatal and can be easily remedied. If you see your fish looking bloated, simply stop feeding it for a couple of days and it should go back to normal.
Why is My Betta Fish Getting a Big Belly?
There are several reasons why your Betta fish may be getting a big belly. It could be due to overeating, constipation, or dropsy. Overeating is the most common reason for a distended abdomen in Betta fish.
If you notice that your fish is always begging for food or gulping down their pellets, consider cutting back on their feedings. You should also fast your Betta fish one day per week to allow their digestive system a break.
Constipation can also cause a bloated abdomen in Betta fish.
This is usually the result of an improper diet or not enough water changes. Make sure you are feeding your Betta high-quality food and performing regular water changes to prevent constipation.
Dropsy is another possible cause of a bloated belly in Betta fish.
This disease is caused by bacteria and results in fluid build-up inside the fish’s body cavity. Dropsy is often fatal, so if you suspect your Betta has this disease, take them to the vet immediately.
How Do You Unconstipate a Betta Fish?
If your betta fish is constipated, there are a few things you can do to help. First, fast your fish for a day or two. This will give their digestive system a chance to rest.
Second, raise the water temperature. Warm water helps stimulate digestion. Third, add some live plants to the tank.
Plants contain fiber which can help with constipation. Finally, if all else fails, you can try giving your fish a very small amount of aquarium salt. Salt helps promote bowel movements and can be helpful in small doses.
Conclusion
If you have a bloated betta fish, don’t worry! There are a few things you can do to help your little friend feel better. First, try feeding them smaller meals more often.
You can also fasting them for a day or two. If neither of those options seem to be helping, you can try gently massaging their belly with your fingers. Just be careful not to overdo it!
If your betta’s bloating persists, it’s best to take them to the vet for a check-up.
