orange domed creature

I had just one when we got our LR, it showed it’s face about 3 weeks later, was rather small then, now it’s about an inch across, and oval in shape. I saw a new small one seem to split right off of it. They are domed ovals with a small hole at the peak. There is a delicate seeming fluted ripple along the bottom edge, it always travels around on the rock, about the speed of a starfish. I have no clue what it could be, doesn’t seem to fit into any class that I can think of? Doesn’t seem to be harming anything, and everything in my tank pays it no mind, but it makes me wonder what it could be. Anyone with any clues, It’s on the back side of a rock right now, so no pic, will add one later though
