Thanks for reaching out about your parrot fish and including a picture. Unfortunately the picture does not help to identify the lesion. There are multiple parasites (and different treatments) that can infest the gills, but very few are visible to the naked eye. Anchorworms would be one such parasite. A short (5-15 minute) fresh water dip can help to decrease parasite loads. Fresh water should be well aerated with an airstone, and monitored the entire length of the treatment. A visit to the veterinarian would allow a gill and skin scrape to identify the parasite, and therefore prescribe a more precise treatment. Good luck.
