I can’t see the picture. If you post the picture so I can see it on my phone I may be able to help. I have nassarius and have had a welk ( it is snail heaven after killing two of my bumble bee snails, caught it red handed with the second)

Its a whelk. VERY similar to nassarius, whelk has no trailing tail and also its' snout is tatooed/printed whereas nassarious is solid colored

Looks like Nassarius to me but have no clue

That is a welk, typically nocturnal. I would remove it before it feast on your snails. Here is a picture of the welk shell I removed.

Here's a nice article with pics by Michael at Aquarium Breeder on the two.

Nassarius Snail – Detailed Guide: Care, Diet, and Breeding - Shrimp and Snail Breeder

Nassarius snails are super easy to keep and feed. In addition, they are very resilient and can tolerate a wide range of water parameters.

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

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:

I agree with @WheatToast ; your video confirms that you have a nassarius not a whelk.

 

[Shibaken3]

lol, I'm getting confused.

 

[Shibaken3]

is it possible that they are not whelk and instead tongan nassarius?

As stated by @reefcleaners in the link, ”Tongan Nassarius” refers to several Indo-Pacific species including Nassarius margaritifer, which I mentioned above.

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

Thank you appreciate it.

yeah, there always in the sand unless I feed them or they get active during nighttime

I know this. They just wanted to know difference. I’m keeping it simple

Look again at snout. It’s the safe version whelk

I’m with WheatToast on this one. That’s a nassarious. I have a couple just like it in my own tank.
