Here's why:
* Suffocation: Snails need oxygen to breathe. A sealed can will quickly run out of oxygen, leading to the snails suffocating and dying.
* No access to food and water: Snails need food and water to survive. A sealed can provides neither, causing them to dehydrate and starve.
* Unhygienic conditions: A sealed can is a breeding ground for bacteria and mold, which can make the snails sick.
Instead of keeping snails in a sealed can, consider these alternatives:
* Aquarium or Terrarium: A properly sized aquarium or terrarium with adequate ventilation, substrate, food, and water is the best environment for snails.
* Plastic container: A plastic container with ventilation holes and a suitable environment is also a good option.
Always remember: Snails are living creatures and deserve proper care. They should never be kept in conditions that endanger their health and well-being.
