Hi. I have a black moor with 2 strange white growths in its side. One appeared a few weeks ago but I thought it was a scale had turned white. After a while it looked like a growth and now there are two. It's in a tank with 2 goldfish and 2 sucker fish. All of them look fine. It is not looking sick. The pet shop wasn't sure but I am treating the tank for white spot but I'm not sure if that's what it is. I though anchor worn but they don't look like any image of worms I could find. Any advice would be much appreciated thanks
