Power outage hit last night at 10:45pm. My tank is in the garage and I have no way to get in the garage. I don't think I my battery powered air pump hoses were in the tank. Are my fish all probably dead? I'm trying to get a garage repair out here to see if they can somehow get it open, but if 9 hours without surface agitation has probably killed all my fish, then I will just wait until power comes back on to see the destruction to the tank.
