Hello, so I tried my Betta in my community tank, and it didn't work out. So unfortunately it is back in it's big vase. I want to provide the best care possible for my betta, so if I change the water every day or other day, will he be ok? I also wanted to make sure what I heard is right. I heard that if you keep a betta without a filter, you should do 100% water changes. This surprised me because the water would be totally different. Also, if I did change the water often, that would prevent against fin rot, right? Thanks, and please answer!
