How does the water quality affect the life of a fish?

Answer 1

It can die. That is the most likely thing that would happen. If they don't die, they can show all sorts of signs of posioning, such as discolored scales, inability to swim long distances, blindness, dysfunctioning gills... the list goes on and on

Answer 2

In exactly the same way that an animal (human) relies on the quality of the air it lives in and breathes. A fish too relies on the quality of the water it lives in and breathes. Poor air quality = poor health. Poor water quality = poor health. In the case of fish though, simply by living and breathing and pooing in the water, Ammonia is produced. Ammonia is deadly poisonous and will kill most living things. If there is no way of removing this poison in a container of water containing fish, the fish will die from ammonia poisoning. A cycled filter uses naturally occurring aerobic bacteria to convert the (poisonous) Ammonia into (poisonous) Nitrite and then into (reasonably harmless) Nitrate. Much of this Nitrate is removed each week when some water should be replaced. Hence the basic rules of fish keeping which state :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank need at least 50% of its water changed every week.. Follow those rules and your fish stand a chance of survival. Fail to follow those rules and I can guarantee failure.
