so I was in a koi store and I hoped they had a few Japanese goldfish like the orandas or buffalo heads ect . They had two . One had 3 or 4 raised spots on its head . I thought it might be ick or a parasite. When I asked him about it he said it was new growth and that it was normal . The fish was completely gold and the spots were slightly raised to a point. Could this be true? I lived on the Ryukin islands for most of my childhood. I know a lot about goldfish but I’ve never herd of that before. I would like to buy it’s tank mate but if one fish is sick I’m not sure I want to take a chance.
