I put my muscaris in the part of the fridge where I store fruits, but I heard that some people store them in the freezer where it's much colder.
However, won't the freezer freeze them to death? Which one is better?
Put them in the coldest part of the refrigerator, which is normally the part closest to the freezer. The freezer would be a little too cold and most of the refrigerator is too warm. 25-30 degrees Fahrenheit is usually best. If you keep your refrigerator below forty degrees, it will probably do fine.
