Pest Anemone

I have seen aptasia but know there are many varities of pest anemone. When I set up my tank with dry rock I did buy 1 lb of live rock. On the rock came soem feather dusters, yellow sponge, pods, bristle worms, neven a reef hermit. Who knows what else but my question is with regards to this dark clearish thing that pops out of a hole like a featherworm would its tube and it dissapears back into the hole whenever the rock is touched. I think it also goes in at night. Do anemones retract into a hole and dissapear like this?

 

Aptasia will when its touched I would get some peppermint shrimp. If its aptasia they will attack it At Least that's what they did in my tank I have been told it is a hit & miss with them so I got 8 of them Good luck

 

It looks nothing like an aptasia. When its out and open it is perectly cicular and about the color of an aptasia but no strands are not thin nor do they go in every direction. It fans open like a fanworm and th strands are very short and thick

 

I know exactly what your talking about they look like anemones but mini... They hide in my rock and come out every once in a while.

Would be great if someone could answer

 

Best bet would be to upload a pic, it will make it easier for people to try and identify

 

Yes very small prob less t hen a 1/2inch across. I have searched the internet to try and find pictures but cant find anything that matches it a couple things were close but nothing to be sure of. I am not even sure it is an aneomone since I never see a mouth. It comes out of the rock daily now when I mvoed the rock it hid for a couple weeks before popping out again

 

I have tried taking pictures but it is so small and clearish that it is hard to get a quality picture to ID with I will continue to try

 

Not my picture

The shape is a lot like the one in that picture only hthe color is more of an opaque pink/purple/tanish color ( sorry color blind here hard to tell try reading test kits lol)

 

Try ball anemone?

 

Not the one I was looking for but you idetified another hitchhiekr on the rock lol. Amazing how much diversity cvomes on 1 lb of rock. Ball anemones good bad or indifferent?
