I did something terrible to Gill

I was getting some water out with a jug, and he swam up between the jug and the side of the tank so I couldn't see him, and he grazed himself all along the side of the tank
I feel so guilty
Is there anything I can add to the water to help him heal and to stop him growing fluff, or getting an infection? Or should I just do small daily water changes to keep everything super clean?
