i.d nassarius snail

[petemichelle]

can anybody help i.d. this nassarius snail. I bought him and about 15 more at my local fish store about a year ago. they seem great and are not the "obsoletus" type. they are about an inch average if not a little bit more. I would like to order more for my new 150 gal but the place I go to for my clean up crew on line (reef cleaners) only list the nassarius vibex that are about 1/2 inch in size. so I guess my question is 3 part.

1. can anybody help id. what I have?
2. are they reef safe and okay to have?
3. where can I get more online at a good price and trust. (when I say trust I mean, trust they are not going to send me some other species or type)

thanks everyone.

I sent this picture to reef cleaners and they seem to think its a Tonga nassarius. They said "[FONT=Calibri, sans-serif]Those are Tongan nassarius, we used to carry them but they were rarely purchased because they cost 4 times the amount of nassarius vibex but only eat twice as much per snail." has anybody had any first hand experience with the differences between the two? especially how much they will eat?

how many should I get for a display tank of 150gal with a 4 inch deep sand bed? should I put them in the sump area as well? [/FONT]

I had a few. They didn't live long. No idea why.
