Snails can exist without food for quite a long time, possibly even months in some cases. You shouldn't start worrying until your snail hasn't eaten for a few days. Your snail may be eating when you are not around. If you only suspect it is not eating then isolate the snail by putting it a clean tank, and place new food in. This will allow you to observe for eaten food and faeces.
