Hey guys, I originally posted this on the "New to Hobby" board but was told I'd have *way* better luck getting an answer here 
I bought some "Nassarius Snails" from a LFS the other week, however I noticed that some of them were colored differently than my previous nassarius snails and had "creamier" colored shells as well as dark bodies (a couple of them are also very large, over an inch in length). I've only recently learned of "Babylonian Snails" which are often sold as "Fancy/Speckled Nassarius Snails" and am now worried that I unleashed a bunch of predatory snails into my tank, especially since my nassarius snail population seems to have shrunk over the past couple of weeks.
A couple of lone pictures (this is not the "giant" one I mentioned, he must be buried in the aragonite somewhere):
A side-by-side photo with a "regular" nassarius:
I also realize I may just be overly paranoid here and that they just may be a different species of nassarius and are "good" snails, however there seems to be about 10+ snails that have gone missing since adding these newer ones (unless they're hiding out in the back where I can't see them) and I just don't think my 3 blue legged hermits could've taken that many nassarius out while leaving all of my astrea snails alone.
More than just killing off my real Nassarius snails, I'm worried that if it is the predatory variety that they will also deplete my sand bed leaving my Diamond Goby SOL (though he readily eats frozen food, flakes, chunks of nori and pellets... Pretty much any non-living edible thing that floats by him).
Thanks!
