Light on or off during the night?

No fish sleep too a regular on/off schedule is best 8-10 hours of light is sufficient for most plants -Anne

Not to mention too much light can lead to an algae outbreak if other conditions are present.
 
I'm no expert, but what i do is turn the light on for the morning feeding, around 6 am just before i go to work, then i feed them again when i get home around 7 pm, then just before i go to bed, usually around midnite, i throw in a couple busted up algae tabs for my silver dollars ( they love them ) then a whole tab for my pleco, then shut the light off for bed. My tank seems to be happy doing this, but like i said I'm no expert....... but I've never had an algae outbreak doing it this way.

BTW it also depends on what kind of light you have, some are designed to promote algae growth, some are brighter, dimmer, etc.

setting of a regular lighting schedule is good for fish, with my experience..I have all my tanks except for my mollie tank setup to a timer.. 16 hours lights on 8 hours lights off.. during the winter i adjust it to 12/14 10/12... depending on the fish and the lighting as said above having the light off can be beneficial to some fish.. my plecos rarely come out when lights on on but at night they are extremely active....
 
i have played around with different watts per gallon. i have 4 wpg which i leave on 12ish hours a day. 12ish hours of darkness. well its never dark in here so some light comes in.

i have observed my fish and they all seem ok. I give them 2 wpg 30 mins before i go lights out or lights on.


never algae just a nasty bacterial infection posing as an algae "black algae" which comes from a plant or fish.
 
My lights are on a timer...they come on at noon and go off at midnight.
 
All of my tanks are on timers also. I do believe that a regular light/dark cycle is at least as beneficial to the fish as it is for people. So, I give them what I cannot always give myself...
 
It's best to turn off the lights at night so the fish can rest and sleep (if they do that). Fish can't block out light because they don't have eyelids, so it's best that you have a regular schedule so there can be periods of light and dark.
