I'm talking about the light spots within the supposed to be dark black rings. Sorry for the late responseI'm having a hard time seeing what you are referring to. I see white in the center of marble spots which looks like normal coloration. I also see white sand on the ray. I can't see much else. Can you take closer pictures.
Anyone else?
Thanks. The health is all I care about. Great news.This is genetic coloring and isn't health related. It's part of the ray's natural pattern. Whether this pattern is a good or a bad thing is open to perception. It's not a sign of deteriorating health which matters most.
