Thats good that you dont see any spots! Ok- in case you need to do this in the future, catch the fish, slightly dry the spot with a cotton ball or q-tip & dab a bit of peroxide on the spot with a q-tip or cotton ball & release the fish back in the tank. You can hold the fish in a towel dampened with tank water if needed. Just have everything set first & work very quickly. It should take less than 10secs to do.
