I am going to just lay it out there... If it is not an adjustable heater then she needs to get a new one that is and can reach 78 so the temperature is where it needs to be or she needs to get a fish that thrives in 74 degree water like guppies. If her fish is already showing signs of being sick having the temperature too low is only going to make it worse.
If she has had the tank for 4 days she should also be doing twice a week water changes. If she has a filter then both can be 50%. If no filter then one 50% and 1 100%. So if it is cloudy she should probably change it every other day until it clears up.
