The biggest issue you may have is ammonia. (Sounds like the QT system was put together rather quickly.) That many fish in a not so established tank can release more ammonia than ur bio filter can handle. Focus on the ammonia badge and be prepared to do water changes more frequently until the bio filter is further established.
Wrasses tend to do better with sand, some actually need it to bury themselves to sleep..
I wouldn’t dose any medication until the fish are eating.
