Changing the water for your betta fish is an important part of keeping them healthy and happy. The water in your betta’s tank can become dirty over time from waste, food, and other debris. If the water is not changed regularly, it can lead to health problems for your fish, such as fin rot, ammonia poisoning, and other infections.
In general, it is best to change about 25-50% of your betta’s water once a week. You can change the water more often if your betta is producing a lot of waste or if the water is becoming cloudy or discolored. When changing the water, it is important to use a water conditioner to remove chlorine and chloramine from the water, as these chemicals can be harmful to your fish. You should also try to match the temperature of the new water to the temperature of the old water, as sudden changes in temperature can shock your fish.
