I've been in the fish keeping hobby for 3 months but I need help so i recently bought a Balloon molly and it was good until I got home in the bag it started to attack the bag and I acclimated it and when it got in the tank it started swarming the corners of the tank and now a week after I bought and acclimated it to my tank it is now being weird it rolls in my tank, and wiggles out of control. Please help I'm concerned for my fish.
