Coral Id?

[ianjirka]

I got this little Zoa rock a few months ago -- and ended up with two coral hitchikers.

First one (1) is some kind of LPS with a Ceroid structure -- very fine tentacles. It's been there most of the time. It's always been brown, but slowly growing.

The second one (2) I noticed just the other day. Any ideas? Should I leave it there or try and frag it?

Thanks much,

Number 1 looks to me like a coldwater anemone species which I forget the name of used to have 3 that hitchhiked on a piece of LR. Dont qoute me on it being an anemone but Im pretty sure it is a coldwater species. Cant see your pic to great but does it look like this?

If so use this pic to get it ID'ed.

Number 2 looks to me like a dead head of the number 1. Kind of also looks like a baby feather duster from a top view of it. Maybe even a very very small species of plate coral. Not positive but I think plate corals grow on rock with their skeleton structure connected to the rock and as they slowly get bigger they detach from the rock which is why you see them singley on sandbeds in the LFS or in peoples tanks. These are just my educated guesses you may want to get them further Id'ed.

I'm pretty sure #1 is not an anemone -- it definitely is laying down a skeleton which looks sort of like a moon coral if the polyps retract (which only happens if they are physically disturbed)



You might be right about #2 being a plate -- it has has extended tentacles after dark, and is raise off of the rock by a small stem in the middle of it. Looks like the kind of structure that would detatch -- I'll keep an eye on it. Maybe separate it into a container so I don't loose it. Will have to find out at what size they typically detach.

Yea I had the same thing in my tank, layed down a skelatal structure which I could really only see when I disturbed it. I had it Id'ed by someone but cant remember what it was called. Your probably right it isnt an anemone but I do think it is a coldwater coral.

If it is a plate it should get decent size before it detaches. Detaching it now being so small you may damage it. There is only 1 LFS in my area Ive ever seen this and they were detaching at about 2" diameter. Ive actually only saw this at my LFS never saw anyone post pics of one. It was a little bit bigger than a baseball size piece of rock and it had about 5-6 plates growing on it. There was also about 3-4 plates same color laying in the sand that had detached themselves.
