Hi everyone! So I have this favia and two of the polyps are a different colour from the rest of the frag. When I received the frag they were all the one colour, but these two have changed. Strangely enough they're the only two polyps that extend feeding tentacles and the only two which will accept food.
It's not something I'm concerned with, they still look healthy after all. Just wondering if anyone knows why this may happen?
