I just added a piece of LR to my tank today and noticed something odd on it after my daylight bulb went off tonight. It glows greenish under actinic light or blue LED's. All I can think it might be i some sort of coral.

almost looks like some zoos that are closed..also may be some type of algea

I think you are right! I've never seen them closed like that before, but I did give the rock a good scrubbing before I added it to my tank.

My actinic bulb went off a little bit ago and it looks like all three are starting to open up more. Maybe tomorrow morning I'll get to see what color they are ^_^
