I have drained all the water out of my 175g tank (right down to the sand) to catch the fish. The corals were out of the water for approx. 3/4 hour with no ill effects.
I have also had my clam out of the water when doing a water change. Do you know they can spit water over 6 ft and very accurately got me square in the face
