(Pics included) Looks like an Anemone? NOT aptasia or Majano?

It looks like some kind of anemone. I know what Aptasia and Majano look like... but this guy has long tenticles and at the end of each is like a little white "ball" looking thing. I thought it was snails eggs or something but when I touched it, it closed up! Anyone know what kind it is? Should I remove it? here's some pics of it open and then closed after I touched it.

 

Google Psuedocorynactis, I have one of the same in my tank, i've kept it in low lighting and fed mysis every now and then and its almost tripled in size ( tip to tip tentacles are about the size of a quarter). They tend to "color up" in low lighting, mine has developed some flourescent green spots.

 

I found one of these in my tank about 2 months ago. It fluoresces under moon lighting. During the day its nearly impossible to see. Never attemped target feeding, thanks for the info.
