My Texas cichlid has developed 2 spots on his face near the eyes, and one has gotten large and looks pink. It has opened up twice and lookes like a crater, then covers over again. Ive been using salt for about a month with 50% water changes avery 4 or 5 days. The large growth has lessened in size, but still looks ugly. The fish is healthy otherwise..good appetite, acts very aggressive towards his buddies. I cant find an example of this disease anywhere. Anyone have an idea what it is? Treatment ideas?
