If you are having an ick outbreak, then a wrasse is not your solution. Y ou must find out what is going on. 1) wrasse have poor survival rates and 2) they can not beat out a severe outbreak of ick. If you have a problem in the tank, then you need to address the problem.
The only 100% proven treatments for ick are hyposalinity and copper.
What is going on in the tank?
How big is the tank?
Other inhabitants?
Water parameters (specific)
For example, I would first say that a clown trigger would be a possible source of stress in the tank and could be the culprit right there. So a complete review of the tank is the best treatment, not a cleaner wrasse.
