Possible coral and tree like thing?

[10nano]

It's that circular thing in the upper part of the picture. It has a stony base with clear tenticles that don'e stretch out very far. It was attached to the LR when I put it in the tank but I have no clue what it is. It has pretty much no coloration on the tenticles other then very tiny white spot on the tips of each tenticle and along the sides. Also the tree like creature in front of the possible coral described above has "fans" on the end of each branch that appear to be feeding in the water column. I though it was a stalk from a plant that had died off during the LR collection but it is alive with lots of tiny tube worm like fans on the ends.

Anyone have any clue what these are?

It looks like an open brain or candy cane.

I bought my LR from a LFS. As for being cured I'm not sure to be honest with you, I would guess not. It is really clean but has lots of hitchhickers: some type of tube worm/feather duster, Emerald crab, a few small urchins that were removed, both of the things asked about in the original post, mushroom polyp (only one), some type of snail, lots of pods and small "critters", and a couple of tiny other unidentified coral.

All this on 9.8 lbs of LR for my 10 gal nano. I'm really happy with the LR. The tank has been running about 3 weeks with only a small cycle that happened during mid week two. Everything tests fine now and I added a purple firefish goby on Monday.

Thanks for the help with the unknown coral ID!

It's a solitary cup coral aka tooth coral. I forget the scientific name. It is most often found on Florida aquacultured rock. Doesn't grow large, or get color, but it is a caribbean coral.

Check out Tampa Bay Saltwater's live rock. That type of coral is often found on their stuff (as was said above in reference to Florida Live Rock). I think they have the scientific and common names listed on the site for the stuff.

When you find out what it is let me know I have about six of them on a piece of LR. They have not really grown much in 6 months but they extend their tenecles regularly.

I also picked up a SPS on a live rock which has regrown tissue all the way down its skeleton and is now about 2 inches high

Cladacora arbuscula tube coral
Phyllangia sp. cup coral
Siderastrea radians star coral

These are the ones listed on the Tampa Bay Saltwater site, I think the one you have is a star coral.

I've got a bunch of these in my tank. They reproduce (if you're lucky) by budding. The best ID I've gotten is Astrangia Sp. Check Eric Borneman's book...there's a picture in there. These are ahermatipic (sp?) corals, so you must have food in the water column for them to live. Mine will take food bits left over from the feeding of my fish, and seem to also take some of the Golden Pearls I feed, even though they are the smallest size.
