What Causes Overweight Betta Fish?
There are various factors that can make a betta fish overweight, ranging from an unbalanced feeding diet to a lack of exercise and unideal living conditions.
I will walk you through each cause in detail in the following sections.
Leftover Food And Overfeeding
The main reason why betta pet fish gain weight is overfeeding.
The betta fish have small stomachs and don’t need a large amount of food to survive and supply for their daily activities.
Therefore, they may not be able to consume and digest all the food you constantly feed them.
As a result, the excessive calories they cannot burn from their movements and daily activities will become fat in their bodies.
Like humans and other species, betta fish require a healthy and moderate diet.
Constantly feeding them with excessive food whenever you get near the tank is a detrimental habit for a betta.
I recommend you feed betta twice a day in small food proportions. You should also adjust the serving portion that suits the body size and condition of the fish.
If you see leftover food in the tank, it means that betta fish are full and cannot eat anymore.
Therefore, you should limit the feeding portion to avoid wasting food and making your fish gain weight.
Lack Of Exercise
Betta fish have an active nature, and they love to spend time swimming around the tank.
Therefore, you should monitor the betta fish closely to check if they are moving significantly less than usual.
If it is the case, your betta fish may be suffering from a lack of exercise.
The possible reasons for this cause can be stress or unideal living conditions. If your betta gets bullied, it will get stressed and become less active.
Also, unsuitable water parameters will limit the activity of betta.
They will have the tendency to eat more and swim less or hide in one corner of the tank, which can all lead to weight gain.
How To Control the Weight of Overweight Betta Fish?
Luckily, weight gain is not a fatal problem for betta fish.
Though it won’t lead to severe consequences, you should not leave the fish in this overweight state for too long.
Over time, betta can get stressed even more and develop many detrimental side effects when they are overweight.
Therefore, you should follow these simple methods to control the weight of your betta.
There are many low-calorie food products produced specifically for overweight pet fish.
They can provide your betta fish with sufficient and essential nutrients without making them gain excessive weight.
However, you must ensure that the low-calorie food product is entirely compatible with betta fish.
Decrease Food Portions
If you see a lot of leftover food in the tank, it means that the food portions you feed betta fish are too much.
Try decreasing the food portions by one-third or one-half and monitoring the fish closely.
You can slowly drop food into the tank to feed the betta fish.
When betta stops eating, it means that they are full, and you don’t need to throw in food anymore.
Maintain an Ideal Water Temperature
As mentioned above, aggressive tank mates or nonideal water parameters can lead to stress in betta.
It would be best if you used a water thermometer to check the tank temperature and make suitable adjustments.
If your betta gets bullied, it would be best to separate them into another tank with more peaceful tank mates.
Why Does Your Betta Fish Have Bloated Tummy?
The most likely cause for the bloated tummy in betta fish is constipation, which is a result of overfeeding.
Also, betta fish can get constipated if you feed them an unbalanced diet that lacks fibrous food.
Another possible cause is a bacterial or parasitic infection. Severe infections can lead to symptoms like a bloated tummy, swollen body parts, or loss of appetite.
If it is the case, you should have your betta inspected and treated.

How To Know When You Overfeed Betta Fish?
The most apparent sign is the leftover food in the tank. You can also monitor the betta body and living habits to look for signs of weight gain.
Overweight betta will become less active and swim in unusual patterns.
What Should I Feed My Betta?
Betta fish are omnivores, so it would be best to provide them with a diversified and balanced diet with both protein-rich and plant-based food.
Some recommended food sources for betta are pellets, flakes, and frozen food.
Why Is My Betta Fish Chubby?
Betta fish can become chubby when they get overweight from overfeeding or stress.
Also, don’t rule out the possibility of bacterial infection and disease, which can make the abdominal part of the betta swell.
What Happens To An Overfed Betta Fish?
Overfed betta fish will have more excess fat on their body and tend to stay less active.
These fish also get stressed and uncomfortable, leading to some detrimental changes in behavior.
How Can You Tell If Betta Fish Is Full?
If your betta fish stop eating or there is leftover food accumulating in the tank, they are full.
In summary, overweight betta fish is an unhealthy condition that you should not underestimate.
Consider reducing the feeding portion and adjusting the tank conditions to restore your betta’s original shape.
Also, the overweight fish will make your aquarium tank less attractive because they tend to swim less.
