Answer:
there’s no universal time period for how long a fish can survive out of water.
Explanation:
The bottom line is that the duration will depend on the species. Some will die in a matter of seconds or minutes (pet fish) while others can stay out of water for hours to months (amphibious fish). One thing’s for sure: Whether you’re going fishing or are simply changing your goldfish’s water, don’t allow it to suffer for long through water deprivation.
