Cover secondary?

[ringo8553]

Is there any reason to keep a carboy secondary in a dark space or cover it, if the fermenting is already finished?

If it is exposed to sunlight or continuous artificial light, for sure. If in a closet or basement w/ little light then no.

Yes, cover your carboy or keep it in a dark place. When light strikes the iso-alpha acids, it will get skunky.

Yes keep it cover with an airlock and yes keep it dark. Light and oxygen are now your beer's enemies

As others have said, light and O2 will skunk/stale your beer. More importantly (in my mind) is the fact that if you don't cover your carboy, you're likely to get some wild yeast (may not do too much since fermentation is complete) or bacteria which will make your day much worse.

+1 to all the above. You can just keep a shirt on the carboy to help keep light out

I just wrap mine in a big beach towel.
