hitchhiker Identification

Hi
please help identify this hitchhiker

Thanks

 

Hmmm...either a large brown polyp of some kind of anemone...hard to tell

where is it? under the sand, is it easy to get to? maybe isolate it before it spreads

 

yes under the sand !! i have 2 on my tank

 

well....if its under the sand...i suppose there is no immidiate threat...but it might be worth tossing...just in case...i am 2 starting to find some small amemones in the sand when i look at the back of my tank under the rocks...no way i can remove them but then again...they are not a threat to anything

 

it looks to me also like some sort of brown polyp if so its prolly hamrless it doesnt really look like a aptasia ive had those in the past there buggers to get rid of

 

It's a button polyp.

 

That thing looks like a brown button polyp to me. Feed it some meats and watch it close and devour it!

 

I vote brown polyp..
