I lost power (suddenly as a matter of fact) for several days to two tanks before. (They were a 55 and 75.) I didn't do anything special partly because it was decades ago and I had no idea what I could do.
I left them alone (no feeding), didn't change any water, didn't do anything special with the filters and didn't have a problem. Maybe I was very lucky, but I don't think 2-3 days is a big deal as long as room temps are decent (75+) and you stop feeding them asap.
I can't speak for the turtles, frogs or shrimp since all I had were fish at the time.
I do think a lot of the suggestions above will be great to employ however especially since there is a small chance that on Monday you find out it will be 2-3 more days. The use of SeaChem Prime or Safe will be useful if you can't get a generator or motorized pumps.
I wish you luck.
