Nassarius Snails

All I’ve done a bunch of research on the Nassarius Snails – especially since many questions have been raised I figured I would toss this info out and if the sharks find it useful they can make it the: Invertebrate of the Week – Critter of the week or something….
The genus of Nassarius is an extremely large genus with distribution around the globe. Ron Shimek wrote and article entitled “Nassarius Snails as Scavengers in the Reef Aquaria” and since publication of that article the gathering and growth of use of the Nassarius Snails in the reef setting has exploded in popularity.
The Nassarius Snail grows to ½ to ¾ to an inch long – depending upon who you believe. They will bury themselves in the upper level of your DSB and stick out their snout (or breathing tube) and wait. They will feed on dead matter or decaying matter and/or excess fish food. They are not Herbivores. Many people claim they are also perfect for cleaning out decaying matter that may be hidden or difficult for other critters to reach because of the location of the decaying material (like in the LR or other hard to reach areas).
They’ll stick their snout out of the sand bed and use it for three things:
1. To move water, and thus oxygen, down into their shells to help with breathing
2. Use it as their “nose” to sniff out the dead or dying food.
3. Provide a cool looking little tube sticking up through your sand bed
Some items you need to know.

All Nassarius Snails will have a re-curved shell. I will post a picture with explanation of the shell which was originally published in Ron Shimek’s article. If it does not have a re-curved shell and is being sold as a Nassarius Snail then avoid it as it could be a predatory snail which will cause problems. It could also be a black shelled Nassarius which is used to lower temperatures associated with the San Francisco Bay area and will die if kept in a tank much above the 75 Degree mark.
The Snails you are looking for are the Nassarius Vibex which come from the Florida/Caribbean area.
The Nassarius does NOT eat algae on the sand bed, rather they keep the bed stirred up thus keep it from getting growth on the DSB.
The Nassarius Snails will not dig down very deeply into your DSB – just the first ¾ to 1 inch of it.
Many people use these critters to replace hermit crabs, but after asking around the Nassarius Snails tend to stay on your sand bed so you need some rock cleaners as well.
The general recommendation is 1 per gallon if you are replacing hermits.

Excellent post! :)
I've got 4 nassarius snails in my 20g. Right when food goes in the tank, they're out. Always on the glass at night. A very cool addition to a reef tank. What are the pros/cons on nass. vs. cerith snails? Bo

Thanks all!! I ROCK!!
OK Bo - Cerith will be more of your algea grazers and these guys wiull stir that top layer of your DSB and they will eat left over food and other decaying stuff that's not plant life (fish remains, fish waste, excess food). Cerith eat algea of differeing varieties. I started looking into these little guys when I started having red slime problems ... they help keep movement everywhere on the sand bed.
My plan is to drop some sinking shrimp pellets in the areaI need stirred and presto they move, devor and bury .... then they often times come out at night and rebury .....
Planning on having about 4 in my 5 gallon and 15 in my 20 gallon.
One thing I neglected to say is that the home aquarium is a good breeding ground - according to research but I have not found anyone who successfully raise them ... yet :)

I have some of these guys in my 20H as well, and I am very satisified with them. They clean the sand bed far quicker than any of my hermits do, and they are pretty hardy IME.
A question that i have is that I have been told that they are capable of reproducing in captivity . . . does anybody out there have any experience with them breeding, or know any more info about them breeding?

If the hermits are hungry they will eat the snails.

To add on to Bang Guy's post - a hermit will eat ANY snail if it is hungry enough!!

I agree that any hungry hermit, will eat ANYTHING, but . . . my hermits dont bother my nass. snails . Infact, if the snail has any food, the hermits just push the snail out of the way. I still have all but one of my nass. in my tank, the one died for unknown reasons, but the other three are still alive and well.
 
I have 25 of these guys and I love them! At feeding time, they slowly rise out of the sand bed, and begin hunting! They usually stay out for an hour, and when the food is gone, it's back into the sandbed..... Awsome scavengers!:D

they remind me of subs breaching when they come up to feed! its soo funny!
as far as reproduction...they lay eggs very rapidly...i find a new clutch of eggs on my glass every day....havent seen any babies running around yet!
however, they are extremely hardy...i got one as a hitchiker in a bag of live sand from the shop i work at..the sucker lived through my cycle...and layed eggs to boot! cool little guys indeed!
good luck

think snail living through cycle is tuff. You are not going to believe this. I went from my 55 to 125 in march. It was freezing at night. I thought it had it all cleand except for some small debris and few shells in bottom. Most everyone went to 125 or into the 30 that i had set up for an in between tank for my corals. It was about a three day move and then I went to take my 55 to it's new owner. My wife pointed out a snail on the bottom of the glass in about 1/4 inch of water. It had frosted the night before. I threw it in my little 10 gallon hp/mini rock reef and it lived. Snails are some tuff little boogers...

Since SWF.com doesn't have any Nassarius snails or Cerith snails, does anyone know where to get any at a good price? I've got a 75G w/ about 150lbs of LR in the tank, and don't yet have a clean-up crew. So, if anyone could help out? I want some Nassarius, Cerith, and Bumblebee Snails, as well as some Blue-Leg Hermit Crabs, Emerald Crabs, etc. Thanks for any help.

Demosthenes - a lot of online places have them ... I'd check hte lfs too since we asked on a local board three places orderd them up for roughly $1 - $1.50 each. I will be picking up 25 or so this saturday from a split order -- Kickster is getting some from me if he every figures out how to hit the reply button in his e-mail.
Demosthenes - if you can't find any sources shoot me an e--mail hilscher@kc.rr.com don't want to post any competitors plus I would not be surprised to see SWF.com start carrying them shortly (ahem - cough cough - wink wink)

Okay, thanks. That'd be great if SWF.com started carrying them. I love buying from here because I know who and what it supports. I found some Cerith Snails from here, and if only the carry the Nassarius I'll be in business.
