Power out

[Richards Aquarium]

I have a 75 gallon DT with 3 Anenome’s and 2 porcelain crabs snails and red leg crabs
Also a QT 15 gallon with 1 watchman gobie 1 hippo 1 lunar wrasse and 1 fire fish.
Will these be ok for 5 to 6 hours without power to the tank ?

What’s ambient room temperature going to be? Watch for increased respiration rate and agitate water if needed. If it’s truly only 6 hours I would not expect issues.

70 inside of house. That's another concern

DT has no fish load, the QT has more.
Put a battery bubbler in the qt.
Or move some fish to DT.

I would be more concerned with the quarantine tank.
As suggested if you have or can get right away a air powered air stone, if not every 20-30 minutes take a quart container ( or any container ) and scoop out some water and dump in back in from 8"-10" above the tank, 4-5 times.
I would also wrap the qt tank in blankets, around and over the top to preserve as much heat as possible.
If you have any hand warmers, put one on each end of the tank.

In January I lost power for 36 hours. My water temperature went down to 62 degree. I have no coral, but I was very concerned for my fish and my macros. However all the fish and the algae survived. Fish stayed hidden in the rocks, could not see them in the dark. Little by little they came out when temperature came back up. All are still fine now.
