Assistant: I think there is some evidence that some species of garden snails are nocturnal, but most are diurnal, which means active during the day and sleeping at night.  While garden snails are still aquatic creatures and tend to live in water, they are generally not very deep water and can survive for a period of time without water.  

An aquarium should have a bright light source, if you would like your snails to be active in the day.  It is not so clear whether the light from a full spectrum fluorescent bulb is the correct type for your snails to make vitamin D in the sunlight.  If you're concerned that your snails are not getting enough vitamin D you can supplement with vitamins D and A drops (of a 50,000 IU/gram concentration).
