How long can fish survive without feeding?

The less food a fish gets, the slower it's metabolism gets. The fish will stop growing with an absence of food. Food is quite rare in the wild for most species. So, even if a fish begs for food, it does not necessarily need it at the time. I do not know the exact timeframe, it is different for every fish. days-weeks is not unheard of.

completely dependent on species and previous diet but I have had a sargent major damsel go for 4 months with no direct feeding. Of course they eat what grows on the rocks etc so as long as your tank is growing algae it should be able to stay alive.

i have left my tanks for weeks in the past with no problems other than salinity issues due to evap. but as said above, the tank was quite mature, so the fish could have found food elsewhere.
