Anemone, dendro?

Sorry, this is the best pic I could get of it. It's on the back of the rock my blue zoos came on and it's only opened a few times, usually when I put food in the tank.

It's much more pink than in this picture.

Thoughts?

Looks like a ball anemone to me. I have several in my tank. They don't seem to cause any problems but the snails avoid them. I'm guessing they sting.

Possibly a variation of a cup coral, I've got one in my tank that looks very similar.

I think BL1 nailed it. I googled cup coral and it looks like some of the pictures that came up.

Thanks guys, I think it's a cup coral too now that I've looked at some pictures. I'll keep a close eye on it.

Ive been spot feeding mine and they've gotten huge in the past few months.
