How much air does my fish need?

[Mike]

I have a three gallon tank with one fish. There is no air pump only a water pump that circulates a small stream of water that flows down from the top of the tank into the main body of water. This is a new tank for me and I don't want my fish to die before I realize it's not getting enough air. Is this small stream of water enough?

I would suggest posting an edit with the species of fish you have. Also do you have a filter? have you cycled the tank?

I think it should, if you believe it disturbs the surface enough it should be okay, depending on the water pressure etc. =]
