How long can the fish survive in the tank without water pump or air?

Answer 1

Bettas breathe air from the surface of their bowl so it really depends on the humidity of the area that the betta is in when it is out of its bowl. If the betta's body stays well moisturized they can at least live two days out of water (conditions permitting).

Answer 2

This is dependant upon the size of the Oscar, the size of the aquarium, the temperature of the water, the organic load in the tank (e.g. dirty gravel), etc. Given a scenario of a 6" Oscar and a 30 gallon aquarium, I would say that CO2 would build up to toxic levels within five or six hours. This time can be extended to days by simply adding an airstone connected to an air pump, however.

Answer 3

Depending on the fish, the size of the tank, number of occupants in the tank, last time a proper water change had been done the exact number of hours is hard to determine. Each case would be unique to the circumstances. Close observation of the tank would be required to properly gauge time restraints. If the fish begin stressing (laying on their sides, etc) a 25% water change would freshen up the water buying some additional time. Keeping the surrounding air temperature a steady temp near the temp the fish require would also help prolong it.
