black shelled nassarius snails diff then white?

[corpusse]

I bought 18 nassarius snails that are different then the ones I had in my other tank. Their shells are black. They are definitely not whelk's as I have seen them submerge themselves in the sand, however they spend most of their time on the rocks and glass. Is this just because I have a moderate algae outbreak? I never see my light shelled nassarius' unless I am feeding or the lights are out. In fact I added one of them to this tank and I've only seen him a couple of times. Of course there are 18 of the dark shelled ones and 1 light so obviously I will see the dark ones more however I'm wondering if these dark shelled guys are as effective as the lightered shelled ones.

those aren't reef safe and are dangerous to softies and clams

they're called ilyanassa obsoleta snails, i bought some off another reefer and had to tear down my tank to get these suckers out

90% sure :) Do a search on various forums and you can see where these comes from...... yes, ebay seller is one of the hottest item.

They will eat your clams, bring diseases, they are temperate snails off the shore in US, usually live around sewage areas. I did an extensive research on those back when I was considering ordering them for $30 for 200.

Oh the last 10%, I am not 100% sure as I do not own any of them myself and I have no intention to, and my research were from various forums in the internet.

in_flight can tell you how his loved to eat his clam, you may try and let us know if yours like your clams :)

i wouldn't intentionally steer anyone on AP the wrong information but from my personal experience i caught these guys red handed or snout to mantle sucking on my clams, i lost a gold maxima clam that i have before i realized what was happening, these guys are bad news

read cellenzweig's post and you'll believe

I never doubed you inflight its just I wanted to be sure before I emailed the store and complained. I am very angry about this they were sold to me just as nassarius snails. I expected them to be the same as the ones I already have.

I demanded a refund which really is a small consolation if they eat anything. Not to mention the time its going to take to catch them.

Surprisngly I was able to catch a bunch of them in only a couple hrs last night however I couldnt find some of them so the search continues.

good luck with dealing with the company..i got all my nassarius from reef raft, they're local and trustworthy

I think another problem with these snails is that they live very short lives in the high (relatively) temperatures of reef tanks. They live ~20-40 years in their natural habitat in cold waters, but only survive about 2-3 years in a reef tank, is that correct?

Sorry for bringing this topic up again, but should anyone see this tread, this info might be helpful.
