Aiptasia, Polyp, or Anemone????

[saul t. waters]

i have these brown polyp looking things on my live rock... they spread kinda quickly...they are about a quarter of and inch round, with lil' tentacles around the disc... the tentacles are striped brown and kinda pink...I figure it be Aiptasia, but it doesn't really look like any of the pictures i have seen... I had a Condy Anemone that disappear, but have never heard of one reproducing, and i also thought it might be brown polyps becasue i had some on the rock when i first got it, but it eventually disappeared and now it is showing back up??? I don't know... <img src="graemlins//bah.gif" border="0" alt="[bah]" /> <img src="graemlins//confused2.gif" border="0" alt="[confused2]" />

I would think if the tenticals are short they may be brown or sand polyps but if the tenticals are long its more likly a variation of aiptasia.
