How to ID critters

We put our LR in the tank on Sunday and found some anemones on 2 rocks. We looked on this site, on lots of other websites, and showed them to a local fish shop. I also posted on the anemone section. I emailed the original rock owner. No one can ID these guys. The do not sting, but we do not want to let a pest anemone take over the tank at this early stage. I hate to yank them out if they are good, but don't want to leave them in if they are going to be a problem. Any other suggestions on how to ID strange animals that show up in the tank? We also have an interesting sand diving snail and 2 different small stars.

Got an ID....
Here is the message.
These appear to have an underlying (calcareous) skeleton... I suspect they
are either single polyp Dendrophylliids or Rhizangiids... Please see the
Net and WWM re. Please see here: http://wetwebmedia.com/dendroidfaqs.htm
 
that's not them...they are just a type of anenomie...they are not bad and really do not spread. I have some in my tank too, generally grow on the shaded part of the rock and I usally only see them open at night. I would not worry about them.

I was thinking they are a type of Ball anenomie (spelling to lazy to look it up again :) )
 
Yes, I think they are a type of cup coral as well. The Tubastraea which is a type of Dendrophylliids. They stay out all the time and do not seem to be effected by light one way or the other. Turbastraea are not photo synthetic so that makes since. It looks like we will have to hand feed them if we are going to keep them.
