Hey Sean,
Since your rock is in your current tank and full of life I would not leave it out of the water for more than a minute. If you have pods, small brittles etc than i'm sure they can't last too long with out water. It took me about 1 1/2 years to get my rock the way I like it and now I'm moving to a bigger tank soon
