Could just be gold scales for sure. Velvet is also known to appear as "gold dust" sometimes, but thats not what that looks like. Keep an eye on it and make sure it doesnt start to spread.
^ maybe, but when he turns he shines like gold... but only the top few line of scales. From different angles, you can see different gold scales. Any other ideas or comments?
And no it's not velvet. I had it before and it's not the same.
