What is this? pest?

Is this a pest , came with my live rock? Looks like some sought of polyp.

 

How long has it been there?...It looks like a bleached polyp...could be aptasia..I have had them look like that after I moved a rock and exposed it to light for the first time...jmo...don't really know.
I'd be more concerned with the algae. : )

 

i was thinking it was a bleached polyp also. That was the first thing that popped into my mind, the other was aptasia but I dont think it is.

I wouldnt really worry about the polyps. You will need to take care of the hair algea on the rock. Try a turbo snail........will work wonders

 

tank is in 4th week of cycle , those polyps were white from the begining , I hardly have lights on. I was told to buy clean up crew after cycle.

 

time for a clean up crew...wont hurt....and watch the polyp...see if it colors up or spreads...not a crisis though...no worries...4th week...situation looks normal. : )

 

what everyone else said, i wonder what it will look like.

 

If I am 4 weeks in will the clean up crew survive?

 

go slow...get some snails, a variety ...hermits crabs are a personal choice..some folks don't like them..IME, never an issue..might hold off on any shrimp or high money stuff..
did'nt catch what size ya got..but thats relative. : )...But go ahead and get some snails in there....just a couple of a few different flavors to start. : ) jmo. : )

 

i have a 36 allon bow front with 45 lbs of rock 20 live and 25 dry , the dry rock is getting full of diatoms ans some green , the live rock i got came with the green hair algea.

 

..it came with algae? That sux... just get a couple turbos as mentioned by schackmel..and a couple other kinds...whatevers available at the lfs...that will do for now.
...also..any algae you can scrape or scrub off easily will help things out (the green stuff)
