There's a few things you can do to reduce the chance of carpet surfing. stick with peaceful species like most Halichoeres; research compatability of fairy wrasses if you add more (they can be jerks to each other depending on colour); stay away from genus Thalasoma. Give them space in a big tank.
In the end though, ALL wrasses are prone to jumping. maybe not now or for several years, but the statistics work against you if you don't have a canopy or tank lid. imo, no wrasse tank should ever be without some kind of protection against carpet surfing.
