    hey guys,
    Ive had a creatchure of sorts for a while now and the first time i saw it (late at night and very light sensitive) i was very excited. I assumed it would perish due to starvation but seeing as it was snuggled between a nice zoa collony (blues) i tried to keep an eye out for it. ive had a few glimses, but they move off quickly, often falling through holes in the LR so getting a photo was impossible.

    Ive been battling with my zoas and thus moved them into a nano tank i have, while all the zoas in main dispaly are gone (or just hanging in there) the palyzoathids are doing fine.

    On wednesday the pump on my skimmer failed so i had to swap the skimmer out and when looking at the life found inside a skimmer i spotted another one on the outside of the skimmer, which i cuaght and managed to photograph. Then today i was cleaning out my return pumps foam on the inlet side and spotted another, so ive fpound three intotal and thats a little worrying.

    anyway, if anyone knows what this creathure is, and what it eats please let me know!

    There are products on the market, but I can't remember the names - maybe someone else can enlighten.

    those are actually cool

    Its big... in terms of flatworms

    Yes she had one in a nano. Then it disappeared until months later. Saw no harm to any corals in that time. Not sure what he eats, but it is not softies, or algae. If it was algae you would see it more often on the glass and on top of the rocks. If softies, no zoa died in that time. Cannot be SPS, as there was none in the tank, but still he survived.

    If you were closer I would take it from you.

    many thanks, polyclad flat worm it is then. Ive lost lots of snails (as in hundreds of small fellas and was rather pleased as they were causing trouble), so much so that I had planned to add a harlequin tusk fish to try controll the snails, so maywell be that these flats have done the job for me, although I am still very suspicious about the zoa collonies, ive lost several and ive always suspected these guys (although i thought i only had one big unn b4!). these seem to survive fine in my sump too and it maybe that they feed on sponges or the like as i have a godo mature system with a wide diversiyty of stuff.....eitherway they seem to be breeding, growing and im not so sure I want em:(

    but thanks greatly for the ID, i'll get onto my friend google and find out about them propperly:)

    Leopard Polyclad

    Hi guys, this may help you here , as well as with a prior thread with quite possibly same species being dealt with.

    This critter looks most like a Pericellis sp
    Which is one of the Polyclad flatworms
    A Leopard Polyclad specifically

    Almost ubiquitous in mildly temperate to tropical waters - so much so - from the Indo-pacific ( ie Across Indian into Pacific Oceans) through the Bahamas, and Caribbean into Florida.
    Quite a wide range hey!
    No surprise they thrive in our aquaria, until starved most likely

    They're SUPPOSED to graze on sea-squirts AKA tunicates
    Which likely accounts for WHERE and WHEN you find them
    Also WHY they disappear WHEN they do.

    Hobby literature including online reports, view this group with caution for aquaria, tending to be referred to as NOT reefsafe
    Then some implicate them in various uncharacteristically predatory roles..ie chowing clams, corals....

    O, and they're hermaphrodites... :blush: I'm sure @viper357 wants to know

    nope, these are BIG things.

    5 to 8cm in length. If they are on your monti, you will see them.

    They are not the normal small almost unnoticeable flatworms that destroy monti.
