Are these Corals? ID help needed!

[chrisncarrieb]

I bought a few pieces of awesome rock from my LFS about a month - month in a half or so ago....filled with coraline algae, and what I thought were coral graveyards. Very interesting pieces. Well I'm noticing some life now! Please help me to identify the following: (I am new to saltwater..and just starting to learn about corals so excuse how I describe things.)
1. A pretty pink coral graveyard...now has new clear tenticles on the end of each tube. I even spot fed some mysis and most of them got a bite! How exciting! I hope they are good!
2. These yellow small egg looking things are sparking my interest. They were sort of there...but popped up. They look like little balls or eggs with a black dot or hole in the middle of each one??
3. A bigger clear thing like in 1 and 5...but the end that its coming out of does not look like either.
4. I have no idea...that seemed to pop out over night. It doesnt move...its not a bug?
5. This is a different rock from different store. The knob end that it is on is different than 1 or 3. All of them will draw in if they sense danger, they are definately alive! Hope they are good!!

the clear thing looks like a glass anemone.

3 and 5 are cup coral i think

Good, Bad, Ugly??? Should I feed them, or kill them?

 

[morval]

nuthing in ur pics is a pest cup u can feed small meaty things. i also have some of #1 and never got a solid I.D. but someone thought it might b a type of galaxea sp but that never looked right to me

Thats obviously some nice rock you got there with all the life you have going on. Glad to see you got some of the good stuff!

You got one crazy rock. I see an orange sponge, and some cup corals on there.

The rock is absolutely awesome! The LFS has like 4 or 5 125gal tanks set up full of this beautiful rock. I absolutely LOVE going there and could spend hours checking out the rock! I certainly have to give them props and have not had one single bad thing to say about them yet. They even had me wait a few days on a fish purchase becuase the fish just came in and was not eating yet. The other LFS around would have gladly sold me this $70 fish!
Since those pictures have been taken, I've found about 3 more of those clear anemone looking things. What should I do? I do not yet have any corals, but would like to start adding some. I would hate to spend tons of money on them to be stung???
And the yellow "egg" looking things are gone. I am finding baby snails...could they have been the snails?

those are not anemone they are hidden cup coral (phylangia americana)

 

[chrisncarrieb]

Are they safe to keep?

 

[reefkprz]

absolutly. here is a little blurb I wrote up on them a while ago as well as a picture of mine
Phyllangia Americana (hidden cup coral)
this non photosynthetic LPS is one of the slowest growing corals I have ever seen. in over 4 years it has only developed 3 new polyps. loves meaty foods and is commonly found on carribian live rock as a hitchiker coral. extremly tough, able to withstand just about any water conditions. commonly mis identified as ball anemone, or hydroids.

I have one also.Here is mine.

I have about 5 in my tank on various pieces of rock...yes from the same store. I love them! I'm so glad they are safe! They must be semi-nocturnal because at night they come WAY out!! My biggest one during the day has its "tentacles" out anywhere from a half inch to inch....at night they are at least 3"-4" long!
