The rocks are definitely covered in some greasy paint and smell of oil. I screwed up the pan trying to cook it as some people have suggested. The color does not come out of my pot. If they told me they were painted I wouldn't order them. Just thought they might be coated with something used for polishing rather than painting. They are good for handicrafts, but not for the aquarium. You can see that underneath the black is brown. They're just painted stones.
