I'm not sure if a topic like this was posted before (I can't find the search button

) but I'd like to ask this section of the forum a question since this is the place to post things about the habitat you made for your betta. How often should I do water changes on a 10 gallon tank and what percentage of the water should I change? I'm sure that you've gotten a ton of this question, but I'm basically blind (Lower than 2.25 vision) and can't find the search button. Thank you for reading this and being understanding about my awful eyes.
