we don't need them, right?

After yesterday shopping I had a question about supraised guest. Turn out it was brittle star. But today guests, I do not think we like them. From craigslist I bought Sebae anemone on huge live rock. But after close look under rock I found that orange something < worm?> and 4 of thouse on the rock< picture 2,3,4< is it aiptasia? Never had it in 8 years reefing.

 

Pic 1- Bristle worm, beneficial.
Pic 2- Aiptasia, none beneficial.

 

+1 ^^^^

 

Shoot. I wish I only had 4 aiptasia. Unfortunately I have somewhere in the range of 50. :-[ But yeah, +1 to the above.

 

Get a syringe and lemon juice, shoot a small amount directly into the mouth of the beasty.

 

+2 ^^^^

 

Lemon juice huh. Currently I'm using the pickling lime mixture but they just seem to be multiplying. Does lemon juice basically nuke them and there's nothing left?

 

Thanks.I just took a live rock out and scraped them < found 8 of them.>. Will see if this work. I still keep that rock with anemone in my Quarantine Tank.
