I'm quite new to the reef tank hobby. (About 6 months). Had my ups and downs with different Zoa colonies. In the image you can see a few Cats Eyes polyps and then that blue "thing" below them. It came with the frag and it was tiny when I got it. It is growing though. There is a similar center "mouth" like the other zoas and it even appears to have the same green-ish color in the center. It doesn't look like it has a stalk and it doesn't close or retract like normal Zoas. It only reacts in a minimal way when I touch it.
Any idea what this is?
