Why Can Goldfish Go So Long Without Food?

Goldfish are known to be able to survive without food for long periods. Experts claim that goldfish can survive up to two weeks without food. This is so because goldfish can adjust their metabolism depending on their need and so do not have to eat to survive.

Goldfish can change their metabolism depending on the temperature of the water. If the temperature of the water is low, then accordingly the metabolism of goldfish will also slow down. A slower metabolism means that the body does not need energy as much, and even all the other activity will also slow down. The body of the fish will be able to function on a little amount of food and thus the goldfish will not need to eat as frequently.

Even though experts have claimed that goldfish can survive for two weeks without food, there is no guarantee that this will happen. Not all goldfish can go two weeks without food and in fact how long the fish will survive without food depends on many factors, many of which may be unknown to the owner of the fish and hence this experiment of not feeding the goldfish for two weeks is very risky.
