So my poor betta has fin rot and he's had it for several weeks. I've already tried salt treatments and just keeping up with water treatments in hopes he would start to heal, but it did nothing so now I'm moving onto another method that was recommended and that was the Methylene Blue bath. So I bought some and I was reading the directions on the back and they told me how much I should mix in, but the duration confuses me. It says use one drop per 16 fl. oz of water daily for at least 3 days and change water daily. I know not to use it in my main tank, so this will be going in a quarantine tank I bought today. What confuses me is the daily water changes. I've googled how long to keep the fish in the tank and some say an hour some say only dip for 10 minutes and this kind of misleads me into thinking I should keep the fish in the water and change the water daily. Can someone please clarify how long I should keep the fish in the water with Methylene Blue. Should I dip him for 10 minutes and return him to main tank after? Should I do it for an hour? Should I keep him in it and change water daily? I'm so confused right now.
