That is my plan if/when needed. I'm still debating whether to only include one and avoid the need to remove when it turns male or stick with my plan and include 2-3 and remove when turned male and aggressive. I have other tank options to separate them, but still don't like an intentional plan that requires re-homing, even if it is after a year(s).
I did not know this for sure for wrasses, but I am already designing and 3D-printing guards for my wavemakers to eliminate the likelihood of fishes blending through them. My 30g desk tank has the first trial guard installed to prevent the odd chance that a small cleaner goby would swim too close and get sucked through...
(This works for the time being, but redesign was needed for a few quirks that did not play out in actuality as well as I hoped in the initial design.)
