Sick wrasse

[Reef addict!!!!!]

Hi guys,
My pink wrasse not sure exactly what type she is has been healthy and happy since I got her a few mths ago I parently put a new heater in so before my old one broke down and got a faulty one. Stupidly I didn't check heat after putting it in I don't know how long it wasn't working corals started struggling I started checking all parameters I could think of and finally discovered it was heater not working obviously replaced it immediately and at this point all fish were fine by the next day both wrasse didn't come out for 24 hrs then 1 came out but not pinky pick wrasse. When she fi ally did she would only lay on top rock and swim of the was touched. Then lay back down. Now 3 days later she hasn't eatten still lethargic in hospital tank laying on the ground. Parameters fine no spots although she looks a little yellow where she would normally be white. Please help what should i do?
Could it be just due to faulty heater should i be treating all fish?

Keep up or add oxygen via flow and even airstone if possible. Turn off white lights for a day or two to keep fish calm and assure salinity is 1.024 - 1.025 and did not change with heater issue
