    Also found this in my tank yesterday...

    It was more or less round-shaped, with the center protruding a bit. Brownish "body " with cream spots.

    Turned my back on it for 15 seconds, and it was gone.

    I thought all stomatella snails have a "top shell" ? and this thing was big. approx 4-5 cm in diameter.

    @Mc,
    Not too sure about that? Could not find anything similar with a Google image search on sea hares.

    It is a flatworm.
    Now the question, which one. But the more important question, what is he eating???

    Hiding away in a tank without being spotted. And the Zoa and mushrooms all do look OK. So is he a good guy that eat algae, diatoms, or detritus. If algae, he should have been spotted long ago as he would have been on the glass.

    Went back in my picture database, and realized that I have seen him before, without knowing it. He was on the inside rock, flat as paper.... But much smaller and lighter. That pic is March 2nd. Unless there are two of them...

    @viper357

    Thanks, according to the Google pics, that is what I have in the tank...

    Now what do they live on? Are they predators? Some confusing info available. Some say yes, others say no...

    Any ideas?

    As far as I know she had not lost any snails. There is one nice big stomatella, a few nerita's and yellow Ring cowries. Plus some minute limpet snails.

    Here is a post in the ultimatereef, looks the same:

    Capturing Polyclad flatworms? - UltimateReef.com

    This guy recommend to let them starve by removing the snails, but they eat pods as well, so will take time. Alternatively a RO dip for the rock if lives in.

    @viper357,
    As @RiaanP mentioned, I have not yet lost any snails.

    I also do not have any clams that it can feast upon, so not too sure what it lives on. If it is pods, well, then it is a toss-up between the shrimpie-thingie and this wormie-thingie for a culprit. I frequently see some pod-bodies floating in the tank, emptied from all juiciness...

    This might end up quite a challenge removing it. SIGH...

    I know Gesiggie did not loose any snails.
    @Len Just a question on that link, any proof that the flatworm actually hunted the snail, or was he a vulture.

    I got Babelonion whelks. And a lot of guys swear they are hunters / killers.
    Actually they are very effective vultures. Anything dead in the tank, and within minutes they are on it. When I add a piece of hake or mussel to the one tank, the one in the remote DSB already pop out of the sand searching.

    Maybe Gesiggie should try the piece of hake and see what happens. If flatworm ignores it, at least her bristle worms would have a feast.
