Look like Nerite snail eggs.

Uh oh, little too late for some of the caulerpa serrulata lol

Thanks to both of you! Of course it is on the back of my rocks :::sigh::: I was able to remove most of it. Will keep an eye out for more. Can this come in on frags? The last thing added to the tank was 3 frags a few months ago.

This tank was set up for two years before I purchased it. It has been set up in my home since March. Last month I had sea lettuce show up out of nowhere. Now this week I have found three other things growing. Looks it the first has been identified as Halimeda. The next looks to be Caulerpa...but how do I tell the difference between Caulerpa and bryopsis? No clue what the third is. Why would all these be showing up now? Thanks for any help!

Thanks! No idea where it came from lol everything I have read says it is harmless, any reason to think differently?

Found this growing in my tank on Monday. Is it halimeda?

I have not personally been to this place, but drive by it frequently in Berryville, VA. http://www.localwoodva.com/Slabs.html

First try at linking a video of this amazing little creature.... http://i1185.photobucket.com/albums/z354/jensforsale1/th_IMG_7287_zpsgcftlrif.mp4

That is it Dave! Thank you so much, I would have not known where to start googling it lol Off to do some more research on it...

Anyone have an idea of what this is? I believe this is at 400x magnification. Sorry for the picture quality, I was using my iPhone through the eyepiece of the microscope. It came from a drop of tank water in an area with algae. I also have videos of it moving/clawing, just need to figure out how to upload them. Just so you have an idea what you are looking at: -it's head is at 7 o'clock position -the dark/reddish area appears to be the stomach -it appears to have legs and claws Thanks for any help identifying it!

Thanks! Fingers crossed they are available this year also

Are the sessions available on CD or DVD after the conference?
