Oxygen Levels: Snails require oxygen to survive, and the surface area of a fishbowl is relatively small, which can lead to low oxygen levels. Additionally, the filter or air pump usually present in a fishbowl may not provide sufficient circulation for both the fish and the snail.
Water Quality: Fish produce ammonia, a toxic substance for most snails. The small volume of water in a fishbowl can quickly become polluted with fish waste, leading to poor water quality, which can be harmful to snails.
Lack of Hiding Places: Fishbowls often lack appropriate hiding places for snails. Snails need to hide and rest during the day, and the transparent glass of a fishbowl provides limited hiding options, leaving the snail exposed.
Escaping: Some species of snails can climb the walls of a fishbowl and may attempt to escape. They can crawl out of the water and dry out, leading to their death.
Food Sources: Fish food may not provide adequate nutrition for a snail's diet. Snails need calcium and other nutrients to maintain their shells and body functions. Specific plant matter and calcium sources should be provided to the snail.
Competition: If fish and snails are kept in the same tank, the fish may compete with the snail for resources such as food and hiding spaces, leading to stress or even harm to the snail.
For these reasons, it is not recommended to keep snails in a fishbowl as their habitat. Instead, a dedicated snail tank or a larger aquarium with appropriate water conditions, hiding places, and a suitable diet is necessary to ensure their well-being.
