Because of my work schedule, I plan on having an abnormal lighting period. Something along the lines of turning on around 12p-2pm and ramping up, then shut off around 12a-2a. Something like that. Will this be unhealthy for fish/corals to have a relatively short blackout period because of ambient lighting? Curtains can only block so much you know.
Also, if I happen to drastically change the lighting period at some point later in the tank life, will that have any negative effects?
