Answer
Jennifer,

When you put add water to the tank you add a conditioner to remove chlorine from the water. What would you add it instead of remove it? You fish are suffering from the chlorine. Do a 50% water change now. Remember to add a water conditioner that will remove the chlorine. Then do a 25% change for 2 days. This should hopefully remove the chlorine you added to the water. I would add an air stone to the tank to help add more oxygen to the water.
