Hello,

Since my fish tank is in the basement (where it gets pitch black at night), should I keep the fluorescent light in my fish tank on throughout the night, or is it ok to leave fish in the dark?

Thanks,

It is ok, actually desireable, for them to have a period of darkness. Like us, they need rest, and dark helps with that.

yea, they don't have eyelids to close, so the darker the better for their night part of the day to let them sleep.

haha, I hear lots of people are "seeing" their catfish blink. I think it's just that they turn their eyes in such a way that it looks as if they were blinking. Although ... I've never had any catfish so maybe I am wrong. But ... I know that none of my fish has eyelids.

And I agree that fish need a period of darnkess as well. How else do they live in nature? They have darkness at night, no? It's only natural that they should rest too.
