Two things I notice - I think your heater needs to be much more submerged than it is (maybe it’s the angle of the photo) but that looks like a fire hazard to me
Two - not tons of surface agitation, maybe with increasing copper you need to add a powerheard pointing to the surface or an airstone connected to an aurpump
I’d test to see what your copper level is to make sure you didn’t overdose by accident
Adding more water or a water change to decrease the copper level may help the wrasse, which looks sort of weak in a way that may indicate a bad reaction to the copper or not enough dissolved oxygen
