id on something growing on my live rock

There something growing on my live rock looks brown..its like a little tube and at the end it has hairs...im trying to get a pic of it..any idea..what it could be.

 

Its looks olmost like a feather duster

 

Google aiptasia. Is it that?

 

yes thats them...Do i need to kill them..and how..i read that there anemone..after i kill them can i now have anemones..T

 

Aiptasia is a pest anemone. It spreads like crazy and kills the other animals in your tank. It's not the kind of anemone you want to keep! I've had success injecting it with a chemical called Aiptasia X. You can buy it at your LFS. If you add some peppermint shrimp to your tank, they will also likely take care of the aiptasia.

The anemones that are sold in this hobby are immensely more difficult to keep than pest anemones. Your tank should be at least a year old before you try to put an anemone in it. I'm sorry, but I feel like a broken record here... Deja vu with your posts about anemones.
