I have hade this little dude in the tank for a while and never really took any notice as it was tiny but I moved a rock today that had been hiding it a little and found that it has grown loads and there are 2 new ones underneath it!
What is it? Its about 1.5 inches across, I have seen it catch food with its tentacles and then curl up to eat it.

Looks like a button polyp to me. It MIGHT be an anemone, but it looks way more like a button polyp to me

I have always told people thats what it was but I recently added some in the tank and they look different. It clearly has a mouth

Yeah, both palythoa and corallimorph anemones have mouths. Many corals have mouths for that matter There are many different color morphs and sizes of palythoa. The term "button polyp" refers to larger browner color morphs and is really just a common name given to the corals you have.

Definately not an anemone. Its a Palythoa. Dropping babies by the looks of it too! Nice!
