    Default Purple Zoanthids - What do you think?

    What do you think they are doing as some fully and others partially retract? These aren't mine, found it on Youtube some time ago.

    Please stop fragging your frags.......you'll eventually do more damage than good. Just let them grow.

    Maybe you got some pods crawling on them...irritating them. I know mine close like that when my pods hop all over them. I have a ton of them and my two clowns won't touch them.

    Neat video...looks like it could be time compressed (ie. fast foward)?

    I think they're reacting to each other

    Maybe they could be trying to get position, sort of like these mushroom.

    I think there is a nudi (or some other very small organism) Crawling around their mat, disturbing their polyps, and causing the polyps to pulse and eventually close.

    There is definitely some sort of Irritation going on.......I think. Reminds me, as it has been a while, to really gaze into my tank a while and watch. Might just learn something.

    They may be feeding and each polyp is catching debris and exciting other polyps. They may also be irritated by something. I've seen this video before just can't remember what they were doing. That mushroom video is neat as well.

    Lots of great observations.

    Yes Mallorie, I have posted this video many times on different boards just to hear the diverse feedback.
