I think ill go with they are safe for now and see what happens once I get a clam. If they go after my clam ill get rid of them. Everyone that helped me out thank you I appreciate it.

Not sure if they would start eating each other, but it looks exactly like my Nassarius margaritifer and is definitely a keeper.
Went back for more pictures of mine:

Have you seen this snail bury in the sand? If so, it's not a predatory whelk :)

This is not 100% accurate, unfortunately.

To confirm - see snout color - Whelk is on the right. Whelk has no trailing tail

its has a tail in his video. It is just covered in sand in the picture.

Looks like a nass to me. Doesn't look like my whelks. The tattoo on my whelk is extremely obvious... like he got a intricate tribal tatoo done. It isn't just brown and white blur.

Nassarius Vibex is my guess. ​

From one of my other posts:
Not predatory whelks. The dark ones are Nassarius margaritifer; I have them in my tanks and they have been model citizens and great CUC.

Nassarius margaritifer (left), possibly Nassarius distortus or a related species (middle), and possibly Nassarius limnaeiformis (right) in my Anti-Reef:

Nassarius margaritifer in my Anti-Reef:

Whelks (right) have distinctive siphon patterning:

That’s my macroalgae/seagrass system where I have been avoiding corals, anemones, and all other sessile cnidarians… except for Aiptasia, ball anemones, hydroids and probably a few other hitchhikers.

I concur, but it's still a good indicator that you're dealing with a carrion feeding nassarius not a predatory whelk.

This is 100% false!!!
Nassarius snails are types of whelks, and all have a "tail" with an operculum attached!

I was thinking about this too. Maybe he was pointing out that the tail doesn’t extend beyond the whelk's shell. The tails on all of my nassarius extend well beyond the shell. Of course the tattooed siphon is a slam dunk.

No, he's just wrong... as usual

I think my whelk has a tiny little snail cover trap door where my nass did not?

Edit: found a photo online of the door

The foot looks tattooed.

I feel like @reefcleaners would be the guy to ask. :)

With that would then be a whelk

OMG! He sent me whelks twice!!

Are you sure your nass didn't have one? Because mine do, even the tiny vibex.

hmm maybe they did then and it was just small. It has been awhile since I had a nass as the wrasses eat em!!
