    Hi guys, last week, i got some new corals from a LFS that i ordered.
    I asked that they gave me the corals as it arrived at their doorstep which they did... (prevents extra stress on corals)
    As always, i dipped the corals before i placed them in the tank...
    As i took the last coral out of the bag, this nasty flatworm was left in the bag...
    It is probably the largest flatworm ive ever seen... About 8cm long.
    My question... What type of flatworm is this.
    Acropora eating type?
    What does it eat?
    Do i have to worry about eggs staying behind on the dipped corals? (used CoralRx pro)

    I have tried finding this flatworm, but everything on the net is confusing around flatworms.
    I have flushed the flatworm.

    And with the tank rebuild did not see it either.
    They are fast and nocturnal. Amazing that something that big could hide for months in a nano before being notices. Not sure what they eat, the zoas etc kept on growing.

    AHHH, yes now i remember... (thanks @Gesiggie)
    It was just such a shock to me that something that big could be shipped with a coral & not be picked up along the way...
    I couldn't find anything on this specific flatworm & one site even said it was a acropora eating flatworm... Which i highly doubt as it was in the bag with a LPS coral.

    Unfortunately i had to flush him as i am busy rebuilding/rescaping my DT & both my other tanks are full of corals at the moment so i had no place to safely keep him till i knew what it was...
    Next time i will keep him in a holding tank & feed him something to see if its a scavenger.
    Thanks guys.

    I also did not have a holding tank, just placed a small piece of LR in a plastic tub, added him, and floated the tub in my tank. They do not like light, and will thus rather hide under the rock, than try to escape.

    So fellow reefers,

    Stumbled across the very same flatworm Pseudoceros Pericelis whilst on my routine bi weekly night inspection and was very surprised to see him climbing inside the shell of a newly shed cleaner shrimp. Was one of the most alien things I've ever seen in my tank.

    After a quick search I was made paranoid by the AEFW wave so promptly found it again. This time "engulfing" a snail :m33:
    (Or possibly moving over it)

    -I have been losing snails like nothing lately and wonder if this may be the culprit, but not sure as I am aware of a little black fingered crab that eludes me!!-

    Regardless I wasn't going to risk losing it as I have not added any new elements to the reef for 3 months and never seen it before. So I chased it onto a removable rock and removed it from the tank

    - but watching it slime its way around the rock I was mesmerized by the fluidity in its movement and chose to infect my quarantine tank with it.


    Curiosity got the best of me.

    I now have it in my quarantine and just want to know if anyone has some suggestions to expand our knowledge base.

    I've seen one of these before, in a nano tank. Not sure what it ate but no snails were lost. Some info on the net tends to indicate that they eat snails. In a nano you would notice losing your snails. And it was in the tank for months. It's camouflage is so good that it was gone for months. Would be great to find out what they really eat.

    Must admit, this is one amazing creature.

    I don't take chances with flatworms..some are harmless but you get some nasty stuff...a friend had two euphyllia eating flatworms he found on a hammer coral with eggs at the base. luckily they are easy to spot as the euphyllia close up.

    Acropora eating flatworms are another nightmare, but only eat acroporas. they can be beaten but takes time and a lot of dipping, natural predation etc

    this "snail" is bigger than the pictures show.

    @Mantra Ray
    Can you please post a picture with something common for size reference.
    Thanks

    Haven't yet got round to setting up photobucket and the whole image post effort.
    Hence the fact that i have no tank shots. lol.

    By the way how does one do the @RiaanP thing??

    The snail it was 'attacking' was around a R2 coin size and was a astrea/turbo.

    Anyone willing to sacrifice a few snails in the name of science :tt2:

    At least we will have a definite answer.
