Sadness and sorrow


I have had my black Niger for at least 4 months and in the middle of no where, he developed some form of skin disease. There is no other way to explain it other than cancerious rot. It started as a small spot (lesion) near the base of his tail (approx 1 week ago). I immediatlely placed him in the qt and began to treat with Melafix. Within 4 days the white "scally" area became raw and spread like wild fire. This am, I could no longer stand to see him suffer, I euthanized him. None of my other fish seem to show any signs of illness, what could have it been? I am truly sadened by this loss
