Thanks for feedback guys.
Well they look more like Corynactis species. They dont have long tube shaped leg. just sitting tight on rock. Are they tread to corals ? They're now really close to edge of rhodactis when it has extended polyps. If so how can I remove them? boil to hell?

I wouldn't worry too much. Just keep an eye on it and see if it starts to irritate the coral. Otherwise, it shouldn't be a problem. My experience with these guys is that they don't like a lot of light and don't become invasive.
