I found this all out recently, maybe a few days ago, but when I brought my beautiful boy Floyd home five weeks ago and put him in a 10g tank he glass surfed a lot and I noticed his fins were tattering after a while but was assured it was NOT because he swam constantly, because he really did swim all the time. All my water levels were perfect and my plants were fine so I knew, even if someone that supposedly knew more than me tried to tell me otherwise, that the constant activity was the reason for the poor state of his fins and also probably not normal. Floyd's behavior became worse until I could legit say he was neurotic which I blamed on poor breeding but it may have just been the size of his tank. When the filter got to him, blew him into the gravel, he got really pissed about it. It was suggested I move him to a smaller tank but instead I divided his tank so he just has 5g now and figured I may as well toss another betta on the other side xD and so I now have Freddie lol I felt really bad about it at first, cutting his previous home in half and taking five whole gallons of free space from him but Floyd does not swim nearly as much now and seems much happier. That is all I ask, that my guys are happy and safe :)
