OK, your sure to kill it?
And if i should kill it, how do i do so?
Just yank it out?

 

[happitylogan]

get a syringe and fill it with boiling water or lemon water and squirt it as close as you can get to the aiptasia. It should kill it. You may need to do a couple times if you see it come back...

I got a couple peppermint shrimp and they ate my aptasia within one week.

they are snake polyps, the second pic. i think.
i had some too. but they died cause i moved them some where with no light and they shrived up and died.
