anemone or aiptasia

[Dougc87]

This isnt my fish tank but I have done all of the research for it. But anyways. Everyday I check out the tank for living things. I think the live rock is more exciting then the fish. I noticed a anemone on the rock one day and I relized that it was the aiptasia so I went to the LFS and bought this stuff to kill it. They even showed us and let us use it on there tank. So I know what the aipsasia looks like but today I saw a anemone on the live rock. It is white with bright white tips. I was wondering what it is. I hope it is a BTA but I dont think it would still be living fro mthe cycle. Here are come pictures.

If this a a glass anemone then I want to make it vanish but if it is a good anemone then I want to stay alive a long as it can.

Thanks
Doug

After looking could it be tube coral? You can't see it but that thing is living in a crater sort of like the moons. I noticed tube coral looked allmost like mine. Mine looks jst like this. http://www.reefcentral.com/forums/showthread.php?s=&postid=7583256#post7583256

Probably cup coral (Phyallangia americana), a common hitchhiker (especially on florida aquacultured live rock). tampabaysaltwater.com has some good pictures of these and other common hitchhikers on their site. :rollface:

After looking around I really think it is cup coral. I dont have a good camera but those pics I took look nothing like the real life thing. This thing lives in a crater that looks like a moon crater. IT is from closed from 9AM to about 7PM. THe only thing that makes me thing it is a glass anemone is that there is only one. All of the pictures have seen of cup coral there is a lot of these little guys around and I only have one.
