Give me a wrasse I won't regret!

I currently have a 75g and I'm looking to add a wrasse. I would like to add a 6-line, but all the anecdotal stories have me scared to add one. :rotflmao:

I am worried about him wiping out my inverts and then being a wr-ass-e to the entire tank.

As far as inverts, I have 1 pretty decent sized skunk cleaner shrimp, a peppermint shrimp and a few nassarius snails and a few margarita snails that have some how been alive for 6+ months.

Would the 6-line really be that big of a terror? There's plenty of bristle worms for it to eat.

Is there a better option?

Thanks in advanced!
