What is on my live rock????

I am having a hard time photographing this tank. I don't know if I am using the wrong settings or if it has something to do with the bowed glass on my corner tank. Any tips would be greatly appreciated

Anyway, we have these guys all over our tank in little clusters. Are they the dreaded anemone that I need to worry about? I am looking at the things on the left side w/ clear tentacles. There is one in the bottom middle too...


TIA!

 

looks like aptesia! peppermint shrimp took care of mine! some say squirting lemon juice but ive never tried it you can look up directions on how to.
good luck

Looks like caribbean star coral.Google it.The nem on the top right is the pest.The rest is free coral.I'm guessing your rock is caribbean live rock.

 

I agree with that.

 

those clear ones almost look like the rare clear frogspawn coral;D you'd strike rich ;D.
i doubt that though lol ...

 

lower left - Pseudocorynactis anemone- stay small, hard to see, not usually a problem pest but can be.
upper right - aptasia - the dreaded anemone, but not a huge deal, common pest.

 

The clear corals look like Phyllangia americana

 

I think Clonefarmer is right or at least on the right track, and everyone else ir right about the aiptasia on the upper right of the rock.

 

Ding Ding Ding!!!
The winner is....Clonefarmer!
Thank you sooooo much for identifying the hidden cup coral
I knew what the Aiptasia was :/ but the others had me stumped.
Thank you again! I feel like I really struck it rich w/ this batch of live rock (minus an Aiptasia or two). There was so much "life" there. We just found a little anemone crab in one of the pieces.
