My ranchu has these white pimple like things on the face. This goldfish does not show signs of trouble or refuse to eat. Does not want to be alone or away from the others in the tank. ( red capped Oranada, Ryukins, Bubble eye, Butterfly calico oranda) and the rest do not show any signs of problems or this issue. Had a prevoius ranchu with this problem and after months on months of treating and trying to help with no signs of improvements but rather start flashing and separated itself from the other I ended up removing that one and now this ranchu has these white things that I can't identify. Have read many things tryin to figure it out but this site had a prevoius thread with a black ranchu and smiliar issues and something about extra blood cells and other non fungus growth..
