ID this one please, good or bad?

Got this snails as part of the CUC, but the guy sold me isn't sure are they good or bad.

Gotta say, not sure. I do not trust too many snails that I do not know. Those could be a type of nassarius, but could also be in the unwelcome "welk" type instead. I would sump them until an expert takes a look. If they are good guys, they will like the sump too.

I just drop them hour ago in a box in the DT with holes on it to get flow in, but till yet they was in another box together with leather corals and the snails which are one post before this (I'm looking to ID both type of snails)

When it is out of shell (opened up, post pic). The tube of a nassarius will be solid flesh colored. Tube of a whelk snail will be marked like tattoo work

unfortunately I was looking for that, but them tubes are too small and I wasn't able to see them at all, tomorrow I'll try to take the macroscope to observe them under in a container with water. Hope that will help me to ID them are they Whelk or no
P.S. So if I understand properly, only if they are whelks I have to worry about them ?

I'll post many photos, which I done days ago, but the problem there is I can't see the snail proboscis at all:
