    Read an article inorousquareium Fish international.it turns out nassarius snails are not clam friendly and are carnivorous. I introduced three to my tank a,few weeks ago and last week the flesh in my,smaller clam dissappeared in a fuzzy mush. Sorry the three snails didnt make it.

    Hmm, I just added 5 of these to my tank. If you don't have a clam, then no problem?

    Went Googling and saw some Threads regarding this..didn't read thru it all but some argue the bottom section I copied and pasted..

    I know this is way after the fact but I want to make sure the correct information is available. Nassarious snails are omnivores, not carnivores. They eat detritus, uneaten food, decaying organics, and fish waste. Simply put they do not attack healthy tank inhabitants. They will however devoure anything dead or dieing in no time flat.




    Clams and Nassarius Problems....

    Babylonia sp. whelks are frequently sold as giant nassarius and are predatory sand dwellers. I had a Babylonia kill an previously healthy maxima clam last winter. The snail im refering to is pictured here, about half way down the page there is a heading Not Reef Safe, the second row, middle picture is the Babylonias that I had Indo Pacific Snails

    I have babelonion whelks.
    And in my opinion they are the best things ever for a DSB area.

    They are not carnivorous, but they are vultures. I feed them and my cerianthus once a week pieces of hake. Must see how fast they pop out from under the sand. And the one is big, when it moves the foot is about 100mm.

    The big problem is, you walk into the room, and OMG, MY CLAM, and all the whelks are eating it. So they must be the culprit. But they are the fastest vultures in your tank. It dies and they there. If mine is hungry, and I add a piece of hake anywhere on the DSB, they pop out and are on it within 30 seconds. Its cool and amazing to see.

    Reason why I like them, they dig into the DSB to hide and sleep, about 50 to 80mm. Popping out when looking for food. Turning the top just enough in my opinion. Anybody who have, I will gladly take them.
    on this link Indo Pacific Snails I got the 5th that's listed under not reef safe.

    If you got them, and you do not believe me, I take them.

    By the way, Cowrie snails are not all under the "NOT REEF SAFE" category.

    I have 6 yellow ring cowries in my 2 tanks. They are definitely herbivorous. But issue is that they are active at night so we miss the beauty. Most cowries are safe, but the bigger ones will cause rockfalls. Yellow ring grow to 28mm.

    Keeping mine with a number of snails. So far never had a problem. Definitely the best sand sifter I have. Also don't drop sand on the corals like some gobies around. ;)
