Conch can live for about three days without water, but if you raise it with seawater, you can live for a few more days, but the conch raised in this way will soon become thinner.

Conch can only live in a salty environment. Seawater is rich in salt, from which conch can obtain nutrients to maintain its own life activities, while fresh water contains less salt, which does not meet the survival conditions of conch.
