ID Please!

[Beanz]

Hey there, I just recently found this little polyp looking thing with greenish tentacle looking things on the outside of it. Just wondering if it should be plucked or left alone. Thanks!

Fixed picture, it kinda looks like a painting by Monet.

Haha, searched it up and was like what does that coral look like lol. ��

+1 on Corynactis, Jewel anemone.

[gobytron]

we're talking top left corner, not middle, right?

[Beanz]

Yes the middle is what I'm wanting the ID on. It does look like pictures I've been checking out of the jewel anemones. Just wondering if they are reef safe now? Or if they are pests like aptasia?

Honestly I wouldn't worry about it at all. I have something that looks the same in my tank and I didn't even know they were there for years. I just noticed them a few months ago but hadn't added anything to my tank in two years and the live rock is seven years old. The ones in my tank don't reproduce like weeds and they grow in shady underhangs. There are only two that I know of.

Beanz, I'd keep an eye on it. I'm not convinced it is Corynactis sp as most (all?) species of Corynactis are temperate, and unless you got rock/corals from a temperate location, then it's unlikely to get one of these critters. Maybe if you have a Gorgonian coral. It might be Corynactis. The pic isn't clear enough to see it well, and there are a lot of little anemones that look like that. Keep an eye on it - if you notice they are popping up babies at a quick rate, then nuke it (Aiptasia methods like kalkwasser paste should work).Soapy's pic is Pseudocorynactis sp, White Ball Anemone. They aren't usually a problem, but in rare occurrences it can become invasive.
