I recently finished cycling my new tank, and started adding fish about a week ago. Today I put in a couple of firefish & after adding them they promptly disappeared into the live rock. While searching for them we found this little anenome with white tips on his clear tentacles. He's only about 1/2" in size and it was hard to take a pic, so sorry if it doesn't come out well. I don't *think* it's an aiptasia, but I'm no expert and I'm not sure. Can someone ID this little guy for me? Is it anything I should be worried about?

If you had a better pic would it look like this (http://www.google.com/imgres?imgurl=http://www.oceanproaquatics.com/pics/aiptasia.jpg&imgrefurl=http://www.oceanproaquatics.com/Aiptasia_Wanted.html&h=600&w=392&sz=42&tbnid=PYdYUKeZdBq3VM:&tbnh=278&tbnw=181&prev=/images%3Fq%3Daiptasia%2Bpictures&zoom=1&q=aiptasia+pictures&usg=__mdmX-PcfRy7x7_1ucgVt-YNhID4=&sa=X&ei=va0aTc2xIYP88AbAnMnCDg&ved=0CBoQ9QEwAA) ?

If so it's aiptasia .....

I am no expert, but I have a cup coral that hitch hiked in on some rock in my tank. It's tentacles look very similar to this. It's non-photosynthetic and hangs under a rock in my tank, grabs food just like an anemone as well. You would need to disturb it with a turkey baster or something to make it retract and look at the base to see if it has a skeleton or not. It's hard to tell from the picture.

No, it doesn't have a "stalk" at all, and its tentacles are clear with little white balls on the end. The aiptasia I've seen look more translucent brown. The balls are somewhat luminescent, so under actinic lights it looks like little white swirling balls. It looks kinda cool under the blue lights actually, although it would look better if it actually had some color.

I'm thinking ball anenome sounds right, although it's not very colorful so I'm still not sure. The pics I found on ball anenomes have some color at the base at least. Mine is almost completely clear.

Thx for the help, I think I'll let him live for now at least.

That's not aiptasia. I also had quite a few at one time. They don't seem to spread.

I tried to blow some water on him and the tentacles retracted into like a base feature (see attached). Now he's mad at me.

I think cup coral is it. Looks just like the cup coral here: http://www.melevsreef.com/id/lps.html Thanks everyone for the help!

I like my cup corals, they catch some of the food that my fish miss and I think they look kind of cool as well. Sometimes I feed them some mysis or something also.

I believe that it is a Ball Anemone as well. The picture was a little rough but take a look at this:

I have some and the base is in little holes in the rock. I found one in the bottom of my overflow and could see the entire creature.

There aren't many really good pictures online of Cup Corals that I can find, so here is a shot of one from my tank.

Great picture! The guy I have looks exactly like that. I actually found another one in the tank as well. The main visual difference between this cup coral and the ball anemone (so far as I can tell) is that the cup coral has a hard base. Also the cup coral is almost completely colorless, save the white ball tips and small white specks in the tentacles.

I need to learn how to take good pictures like that. It would probably help if I had a decent camera...
