Is a Sixline Wrasse a danger to nassarius snail(s)?

[jigga w00t]

After a recent outbreak of yellowish-brown flatworms, I bought a sixline wrasse and I'm crossing my fingers it will eat them. I don't think it has so far, but it's only been a couple days. Anyways, I fed the tank, a nassarius snail was in turbo mode looking for food, and I notice the sixline eying it.
Then he just swims right at him and nips the snail real good. After 10 mins, it was still pulled in its shell when I checked back. All sixline owners know how active they are, but its hard to tell - do sixlines have teeth? I'd hate to think he would slowly kill the nassarius by taking a chunk out of them bit by bit...

My sixline hasn't touched a thing in my tank other than food and probably hard on my pod population.. but I've heard of some aggressive ones out there.
The hardest thing I've seen on my bristleworms is my coral banded or cleaner shrimp. I've never had flatworms though

mine always bites at smaller stomatella snails. he hasn't killed or ate any but he has made a few fall off and pecked them good. doesn't mess with the astrea or cerith snails I bought.
