    Snail one looks like one of the abalone specices. Hard to tell from the pic, can you perhaps get one of the top of the shell.

    just looked it up def one of those thanks :) and on that page the second one might be a bumble bee snail ?
    So both those snails won't be the guys eating the Zoas right?
    There is one more snail but can't find it will look for it tonight and the other ones are 2 large turbo snails which won't be eating them either.

    Then it must be one of the dozen of crabs in the tank :(
    Is there any crab in particular that is prone to eat zoas ? And I also have 3 different types of hermits

    The last one looks a bit like a sundial snail, do a google image search and see if you think it does.
    If it is a sundial snail it could be the culprit they are known to eat zoas.

    Just looked them up no never seen any nudibranches. I got quite a few vermitid snails but they shouldn't be the problem either.
    Will try take pics of the different crabs tonight there's all sorts but they so hard to get out but guess i'll have to take them all out afterall cause that's then the only thing i can think of that could be eating them.

    THe abalone wont touch the zoas.
    The second snail is not a sundial.
    Check after lights out and see what is crawling around the zoas.
    You dont perhaps have any fish that could be pecking them?

    Second snail is not a bumble bee. the yellow and black bands should be uninterrupted.

    More likely a Muricidae snail, and they are predators on other snails.
    Muricidae Snail - Warning - Marine Aquariums of South Africa
    Although the culprit in that thread do not have the yellow markings.

    But if I remember correctly you got live rock in directly from wherever with loads of life on it. Are these snails hitchhikers? Could explain why second snail is different compared to our local species.

    The last picture? is it a flattish disc shape snail? The opercolum have a sharp pointy end when the snail retracts? (that is the flap closing on the opening when you pull the snail from the rock)

    Thanks Riaan :)
    So the snails can stay. I tried to see what was by the Zoa last night but when I wasn't watching for about a hour inbetween there was another bulb gone :(
    Is it difficult to spot a nudibranch if there was one?

    Buccinidae

    So not sure. I have whelks and they are extreme vultures. Can test it easily. Put small piece of hake on the substrate. If the Engina finds it pretty fast, then its surely a vulture and nice to have. If it ignores the hake, even if you place it next to it, then you should start worrying.
