Aiptasia?
 

just noticed this, im assuming it is, i know there is another one the same, that is living inside a hole on a near piece of live rock - as well as one i have growin in a 5 gallon for the fun of it.
Im asking cuz i usually see Aiptasia as taller polyps, all these ones are flat against the rock with just tenticals out.
not to worried about them, either break them off and throw them in the 5g with the others or get a peppermint or two.

Looks like it to me.

well i torched a couple on the easier pieces to pull out and grabbed some peppermint shrimp.

K well #$% - i knew that wasnt a for sure thing with the peps and eating them. but well my 6 line wrasse just went all nature channel on there asses, seperated them long enough for them to hide, but hes still on the hunt - that was an expensive meal..

easy mix some kalk paste and smother the thing.

well one pep shrimp managed to live, and still is alive - only comes out at night im assuming though. he did eat all the aiptasia though :)
