A couple of weeks.
Sheep can survive without food for a couple of days. This may vary depending on the type of sheep. It is said that sheep can last even longer without water for up to 3 weeks.
A human can only survive 1 week without water, and 2 weeks without food
Sharks can survive for up to 6 weeks without any food. However this time frame has been debated and new studies show that they may only be able to survive up to 2 weeks without food.
Of coarse they would, we humans can survive weeks without food as long as there is an intake of water.
If properly hydrated, a healthy male can survive for about 3 weeks without any food.
The exact time varies depending on individual factors, but most people can survive without food for about 3 weeks. However, it is important to note that water is essential for survival, and a person can survive only a few days without it.
About 2 weeks :) <3

In general, humans can survive for two to eight weeks without food, depending on stored body fat. Survival without water is usually limited to three or four days.Source: http://en.wikipedia.org/wiki/Human
Oxygen, Gravity, and Weed. 3 days without water and 3 weeks without food
That depends completely and entirely on the tank. In a freshwater tank with anything besides lightly stocked algae eaters, I wouldn't go any longer than a couple of days without feeding. Of course, they could survive maybe a few weeks without food, but that would be cruelty.
