couldn't do anything Its been swimming around a lot maybe it hit the tank?

  • Welcome to pets.SE! If it is not constantly rubbing this spot onto something, then it is some kind of skin infection. If you did not sat it in a tank to other fish, you should not do it. Instead have it in quarantine, until you know what exactly it is and started treatment. Jun 26, 2023 at 5:40
