Is this snail predatory or not?

Nassarius snail. Great sand sifters and detritus eaters. Harmless.

Hey Jamie, I don't think it's a nassarius snail, cause the shell is more slender and the tube on the nassarius looks alot longer and not striped like this snail.

Heidi I have one in my frag tank and it's never touched a coral.

Do they submerge themselves in the sand?
