Haha, I knew what you mean. I just wanted to give you a hard time. Before I had my timers on, and would leave the lights on for 16+ hours b/c I was barely at home due to school and work, I'd come home to find my fish looking stressed out and pale constantly. They stopped behaving this way once I put them on a constant light cycle.
There's typically enough ambient light in a room that an actual light strip isn't needed for them to know whether it's night or day.
