What is your personal experience with them? I have a bunch of these that are doing great in 77 degree water.

my experince is they last for a while, but at about a year you notice the population starting to decrease to nothing. They just are not ment for our tanks....unless you like to look at snails as a resource that constantly needs repleanising.

Well I'm not sure what the typical life expectancy is for snails, but at a cost of about a quarter a piece on eBay, it is probably a good deal since they do a good job of keeping sand clean.

Someone also mentioned the the Illynassa come from California. Which I guess is partially true since they do live there as an introduced species, but they are from the Atlantic and everyone on eBay who sells them lives on the East Coast.

That's because they also come from the northeastern parts of florida....but just because something comes from an area that most people associate with tropical weather does not necessarily mean it is tropical. A good case in point is the white bar boxfish from Australia.

I have also read they inhabit areas near New York.

They were supposedly introduced into California on oysters...I have no idea how they were introduced into other areas or where exactly they originate from. I can tell you that the information I read states they are somewhat predatory and that they have pushed back/killed off some of the native life in the areas they have innapropriately been introduced into.

i just bought some today, how long do the live in nature then? more than a few years?

The article I posted says they live 5 years but I am far from an expert on these things so I couldn't tell you for sure.

just speaking from personal experience and not trying to dispute anything that anyone has said here but i had over 100 of these guys in a 50 gallon reef i had the cleanest sand bed anyone had ever seen these guys would pick off all debris of leftover food items as well as any algae that started to form, i had absolutly no algae in the tank the enitre time they were in there and once per week i would give them a cocktail shrimp.
At one point i had a damsel fish that did not look like it was doing very well at all he at some point either died of natural causes or just laid down on the bottom of the tank and let the snails take him (lol), to me this was awesome no worries about a dead fishing hiding in the rockwork and rotting throwing my water quality out of wack.
They were awesome little snails i called them my little soldiers everytime i would feed the tank they would rise out of the sand like an army they worked for me in the past and as such i am now waiting on another order of 100 as far as what happened to the first order yes they all died ( or at least the ones in my tank) i gave a great deal of them away and traded them for frags and i know of at least 2 people who got some from me who still have them in they're tank for almost 2 yrs
