Tell me this isn't Aiptasia!!

[hillbillyreefer]

Nervous Nelly here again. I have these anemone looking fellers in my tank. I have a bad feeling it is Aiptasia but want a second opinion, before I open a can of whoop a$$ on them. Some of my research says they are, some says they aren't. Meleve has a picture of one that looks close but all the rest of his pics don't resemble what I have. For what it's worth one is growing beside some leathers and appears to be stinging the crap out of it. What ever it is it needs to go. I've taken several pics and will post up the best one.

Thanks in Advance,
