Chocolate is very sensitive to temperature and humidity. Ideal storage temperatures are between 15 to 17 Celsius (59 to 63 Fahrenheit), with a relative humidity of less than 50%. Florida, for example, is very humid, exceeding 80% humidity outdoors, at times.
Chocolate should be stored away from other foods as chocolates can absorb different aromas. Ideally, chocolates are packed or wrapped and then placed in proper storage areas with the correct humidity and temperatures. Putting chocolate in a refrigerator is not a good idea unless you have no A/C under 70 Degrees. The Cocoa Butter will float up and make it look funny. Still good--just an appearance issue.
