Hello everyone, I need some help. My Tang Desjardinii has had a large black spot on its belly for about 2 weeks, and it's growing. It is swimming and eating well, with normal breathing. It is well adapted to the aquarium, peaceful, and has been with me for over 3 months. I did QT when I first acquired the fish with cupramine and prazipro. I feed my fish by alternating Vitalis pellets, artemia, mysis, and spirulina 3 times a day. No other fish is showing similar changes.
