    orange rocks under lunar lights?

    I'm noticing at least 3 or 4 live rocks that glow a fluorescent orange under my night lights.

    Anyone else notice this? Normal?

    I've notice that too but mine is more a flashy red,almost fluorescent.

    I too have no clue what it is.

    My live rock is from mixed sources and it has bright orange and lime green colours that do glow. this is just different types of coraline algea. Its been in my system for more than a year now.

    Mine seems to be almost like inside the rock or in all of the cracks / holes in the rock.... very weird glow looking. Almost like the rock is glowing. I will attempt to take a pic of it and post it but not too sure if it will show up.

    I guess as long as it is not a dead rock or some sort of bad disease then I guess it's nothing to worry about.... i guess.

    From what I have observed over the years it goes something like this...
    I turn a piece of live rock over or take froma darker area of a sump, or some such thing. Always a peice that has received little direct or indirect light. The coraline (some different sp. than purple) flouresces for a few days maybe a week and then dies in the presence of high light. Enjoy it while it's there.
    But yes to make along mundane post short, its coraline.
