Tips on Controlling a Betta Fish’s Weight
Tip #1: Use Low-Calorie Fish Food
If you are asking, “Why is my betta fish getting fat?” then it’s time to start here.
While fish food is essential, this doesn’t mean you give any type to your betta fish. It’s essential to find a verified, well-regarded solution that is low in calories.
There are several benefits of pursuing a low-calorie option for your betta fish.
These benefits include:

This is what you have to aim for as a fish owner when the weight continues to go up.
Tip #2: Reduce the Portions
The portions are often the main reason for a betta fish gaining weight.
This means you should take the time to reduce the portions by a little. To do this, you are going to have to measure the betta’s fish food and make sure it is the same amount every single time.
From this point forward, you can make subtle adjustments downwards.
Remember, this isn’t going to happen overnight.
You will have to stay patient and make regular checks on the portions to ensure they’re consistent. Once you do this, you will easily start seeing a positive change in your betta fish.
Tip #3: Reduce the Water Temperature
When the water temperature is too high, this is going to have a unique effect on your betta fish.
In some cases, the water is way too hot and that can kill your betta fish. However, there is a middle ground where the betta fish is going to start to gain weight due to the conditions, especially if it is well-fed.
This is not a good thing as it is not natural to the betta fish.
You have to regulate the water temperature or the betta fish’s weight is going to spiral out of control.
It’s essential to take regular measurements to see what the temperature is in the fish tank. This is a must and should become a part of your routine every day.
Tip #4: Keep Visual Records of the Betta Fish
Why is my betta fish getting fat?
In general, you shouldn’t have to ask this question when you are keeping track of the fish’s food intake. Unfortunately, it’s difficult to do this and a lot of fish owners don’t have the energy to focus on what the fish is eating.
However, when it’s time to make changes, you are going to need to record each detail.
This means more than just taking out a journal and jotting down the portion sizes! No, you have to start taking pictures/videos to see how the weight gaining is going for your betta fish.
If there are limited improvements in the coming weeks, this means further changes have to be made. A lot of the times, your first adjustment isn’t going to be enough.
