The Electric Mains

[sparky_555]

Hi, there are a couple of light sockets in my house that need replacing, while that is happening (tomorrow) the mains are being cut off which means the filter and heater in my cycling tank wont work (i'm guessing for about an hour).

Will this be a problem for my fish?
The fish i have are:
3 black widow tetras (been in for about 3 weeks).
3 bronze cory's ( been in for about a week).
And 1 bristlenose plec (been in for about 2 days).

Thanks

Not a problem. What size tnak is it?

Its a 20 gallon, i wasnt sure if the bristlenose would be too big (i got it off a friend who has a bigger bristlenose that kept picking on it, mines about 1.5 inches at the mo).
It only grows to about 4 - 5 inches? is that still too big?

an hour is fine, your tank should be ok for up to 12 hrs with no power, after then the filter bacteria dies off
