hey my 3 1/2 inch oscar has a scrape on top of his head idk how he did it, i just noticed it when i came home from school. My main question is what is the best plan for action in this situation? my tank is at 87 degrees atm and has 1tsp of aquarium salt per 8 gallons atm, is that enough to help heal the cut or do i need somethin else. just trying to find out what to do so that i don't loose my lil oscar.
