Okay. Some of you may or may not have read the thread about my fish tank being foggy. Might I add, I do do 25% water changes once every week-two weeks. But this spot has popped up on Wartooth's face. It has been there for about three-four weeks has has grown over time but he has shown no signs of illness. I keep forgetting to buy him some meds but I have been adding salt. At first, he had fin rot and I took him out of the tank in case he was contaminated and put him in an emergency tank. Left him there for about 7-10 days. His fins stopped shredding off (rotting) but the spot never went away. He eats normal, acts normal. Dances when I come to the front of the tank. So what is this? What kind of meds should I buy? This is really worrying me.
