So I have this pink tail trigger fish he is pretty big about 3 inches he has ich and I know it but it won’t drop off of him he had it on him for about 6 days at water temp 78 degrees he is eating very good very aggressive eater and sometimes I notice him just swiming in place at the bottom of the tank and other time he is swimming doing normal fish stuff. Just want some feedback/ suggestions and I have no room for a qt tank
