    Q: anyone know what these are?

    I have two of these red things in my tank - one on the rock and this one that appeared on the glass while we were away this weekend.

    And they move!



    Thanks,
    Andrew

    I looks like it might be a Majano anenome or some sort of mushroom.

    It's not like lightning but it definitely moved on the order of 6 inches in less that 30 minutes.

    Any insights appreciated!

    Thanks,

    I'll hazard a guess that it's a baby sea urchin that hitched a ride on your liverock...
    Do you see any "sticky feet" as it moves?

    The pic shows tentacles (I am assuming that we are looking at the underside of the critter) the speed at which it moves indicates that it is most likely an anemone of some kind. Could you take a Pic of the top of the anemone? A Majano will look like a miniature Buble Tiped anemone when mature. When very young they look more like a brownish zoanthid.

    I hadn't noticed - the one on the rock has been there for AGES and never moved/grew - it looked like a nondescript elongated blob.

    The other one was round and at the waterline and scooted right along.

    You are actually looking at the "top" - it was at the waterline on the glass. Come to think of it - it does kind of look like a reddish zoanthid...d'oh!

    I haven't added any rocks for ages - can they lie dormant for a while?
