Snail ? Good or Bad

[yycguy]

Just a photo from my IPhone ...
Any idea if these guys are good or bad? I have several that have spread now in my mixed reef.
Thx for any info

hard to see in the pic - he might be a bumble bee snail

If it isn't black and yellow but a tan color than it is looks like a nassarius. Good guys!
