How often do I clean my betta fish tank?
You need to clean a 5-gallon tank weekly, while a larger 15- or 20-gallon tank only needs cleaning once or twice a month.
Do betta fish need their tank cleaned?
For a 19 litre betta aquarium with just a betta fish and a filter, you’ll only need to give it a full clean out every 6 to 8 months. Some planted aquariums with a good filter and a balanced ecosystem of ‘clean up’ tank mates can go years without a clean.
How do you change a betta fish’s water?
The best way to change your betta fish water is to replace small amounts each week rather than replace all of the water at once. Add the fresh water to a clean container, mix in a water conditioner, and let the water sit at room temperature for about an hour.
