Need ID - Seems to be Aptasia

[bunywail]

I have some critters growing larger every day on two pieces of LR that came from the same LFS. I bought the rock about 5 months ago, but these critters started growing like crazy once I installed my homemade moonlights.

I think they may be aptasia, but I have no frame of reference, or experience to help me make a positive ID. I explored the message boards and have seen some posts on this, but there's lots of ambiguity. For instance I saw one post with a photo that contained a specimin just like mine - and it was ID'd (though not definatively) as "one of the good guys." Let me know what you think, because these guys are getting large and I want to take care of them now . . . . . . unless they aren't aptasia.

Thanks in advance!!!
