If you have a pet snail, try giving it some food with water already in it (like lettuce leafs). Another good idea would be to get a plastic bottle cap (so it won't rust) or something similar. I use a checker-piece for my snails and fill it with tap water.
Also, snails like to eat other fruits and vegetables. I've heard they like apples and carrots a lot. I know my snails like carrots.
A guinea pig water feeder or a water bowl.
You don't need to put a water bowl in the cage. Just moisturize the tank 2 times a day. Also make sure it is only rain water.
They get their water from licking at the drops of dew on the leaves of their natural habitat (trees) - they rarely venture onto the ground, and wouldn't normally drink from a bowl.
Always keep it in water.
yes but only salt water
You would need to pour the water into the bowl.
No, garden snail eggs do not need water to hatch. Snail eggs require a humid environment to prevent them from drying out, but they do not need to be fully submerged in water. The eggs can be kept in a moist substrate to ensure proper conditions for hatching.
Garden snails do not drink salt water, but they will drink water. Garden snails will drink any water that crosses their path. Snails can not drink salt water because it dries out and shrivels up their skin.
They need it for when they come on top of the water
I don't need to drink if you are drunk. You should drink water.
They don't need to drink water since they live in water.
You need to moisturize the tank 2 times a day if it is a garden snail.
