Water has oxygen dissolved in it. It gets this oxygen from plants, agitation, air stones, air to surface transfer, etc.. Fish require oxygen to live. If there was actually no oxygen in the water, the fish would suffocate in minutes. Otherwise it would depend on the amount of water, the number of fish, and many other factors.

Without oxygen or without filtration? Without filtration, they will survive by staying at the top of the tank gulping air until they have what they need to go about their swimming. That would take a heavy toll on their rest, and make their lives very uncomfortable. No oxygen, and they'd do the same for a short while, and then try to jump out of the and tank until they chock to death one way or the other after about 30 minutes.
