It does depend on your fish. What you should do, is test the ammonia every day. When ammonia shows up, mark how long it took, and that is how many days the tank can go without a complete change of water.
Cycled tanks are a different matter. They only need occasional partial changes.
Once a week.
Never. You should change the water a few times a week if the bowl is not filtered, but do't completely clean the blwl or wyou will destroy the benifical bacteria that converts ammonia and nitrite to nitrate and o2

If you don't see it, go to options and click "Try Beta" button. That's all.

Possibly bad water conditions or shock from a badly performed water change or maybe it has been netted and handled roughly.
