I have the biocube 32 and 4 clownfish. I know fish sleep. But my lfs said to leave the light all the time. White in the day and the blue at night. But I read online that if I do that they will stress and die. So which is true do I leave the lights on all the time, or do I have the blue light on...
I captured this photo of one of my yellow staghorn damsels trying to blend in between my nepthea and rock last night. Any of you have neat pictures of your fish "sleeping"?
