Ball anemone. Reef safe. May sting corals, but generally only grow in shaded areas.

I had one that split a few times over the years. It didn't require light, so it hid behind the rocks and only opened at night. They are Very Sticky. I introduced a wrasse to the tank one day and it was having a tough time acclimating. I went to check on it that night and found it stuck to the ball anemone. It was too week to escape on its own. I got the wrasse loose, which eventually perked up.

I moved it to my sump and won't be putting it back in the display tank. Although it was fine for several yrs with all my other fish. I just don't want to take the chance again.

Mine gets to be about the size of a quarter before it splits. It leaves buds like twice a year. And they take a good 6 months to grow to full size. This is without any direct feeding. So, in my case, they are slow growers and not a threat to take over the tank. But again, I don't recommend them around the display fish.
