Hello, I hear fin rot is common I also hear it is not hard to cure. I know nothing about it so this could be completely wrong. So I would like to ask you all to help me identify it and also learn about how a fish gets it and I. The worst case scenario get rid of it. Ok fist off I work a lot so I felt bad for my betta (Yes I know how insane I sound) so my solution was to get a pet for my pet I researched and found that planta faith make great tank mates for betta, one because they are small and smooth with no large fins fluttering about tempting my betta to go after it and two they and passive in nature. The short long of it is I bought one Saturday. And my bettas good with it well getting there lets say he chased her everytime he thought he was about to be fed. Day by day he's becoming more sharing. Now could of this fish brought fin rot to my tank? And what can of disease can be cared over from on tank to another also is it something that happens offten and is their anything to prevent it or at least better my odds of preventing it ? Lastly I read planta fish should be in groups of 3 to 4 so would it be a good idea to go get another one?
Thanks for your time please help me learn about these issues and please take a look at the picture and tell me if this could be the early stages of fin rot
