FYI, most of the ones I put into the reef system are dead. The ones that are in the (unheated) holding bucket are still alive. If you want these guys as feeders, best to keep them cool and not put them in a warm tank.

Christy,
How long after you put them in the reef tank did they die?
Mine showed up last Monday, I put them in a container and added salt water from my makeup system. Kinda forgot about them for a few hours, went back and flushed the container with fresh salt water to clean out any detritus and mud. and then divided them up between my tanks. I put 10 or so in my 37 gallon F/O and the tank has never been cleaner. I put the remaining 100+ in my reef, and I think the majority are still alive and cruising all over. And there are allot of eggs all over the glass.....
I think the only fatalities, were hermit crab induced, and I think the Sally Lightfoot took a couple out.

I got them in early January--just a few weeks ago. They seemed to be fine for about 3 weeks, then started dropping off very rapidly. Now, I only see 1 that's alive. I have no sand, so they aren't hiding in there. Looks like I have a lot of shells to clean out though! My astrea, turbos, and nerites are ok, fwiw. I am surprised that the mass die-off didn't throw my tank for a loop.

My mantis has enjoyed live food for a change, so they weren't all for waste. I've still got a hundred or so in an unheated bucket, guess I'll just keep them there.

my snails are under the sand at all times with their little syphon out i guess because almost instantly after i add food or move around stuff they come out like zombies in a movie and if they find food (shrimp, or formula 1) they eat it up. i have never seen them eat algae. my limpet and other snail actualy eat tons of algae.

as far as mantis shrimp. i still dont have one.

Mine are still alive and thriving, very active all over the glass and sand. My mantis just ingores them, And in the reef tank they are too small for my hermits to care...

These snails need sand to be happy and to rest.
The eggs never mature because of the stages they go through growing up cant be supported by the food chain in most tanks.
These are cold water snails and dont have good long term survival over the years.
As mantis food they must be the best option you can find. A good place to keep them before feeding would be a refuge.

I have ordered them(Atlantic Nassuraus) twice in four years and have a tank that supports Ceriths breeding to the point of haveing thousands of rice size baby Ceriths. With this being said the survival of these nassarus is very low over the long term. But as a food source for your tank they are awsome
