I noticed this lesion on the side of my purple dottyback today. Fish is swimming/behaving normally and eating well. All other fish are healthy. Tank parameters all within normal range. He is very protective of his corner of the world but is not overly aggressive to tankmates otherwise. Any idea what caused this lesion? Treatment?
