Consider this: a number of years ago I recall my family would put in night lights that were a small ity bity 15 watts. they were just little plug-in-the-receptacle type of lights. Some had a small switch on them. But today, for that same 15 watts you can get a LED floodlight. So lighting today has changed drastically. In my fish room I have two of these very small wattage lamps that are at the ceiling in the center of the space. One is only 7 or 8 watts and its as much light as a 60W incandescent. This one remains on 24/7 The wattage is just so small. no need to ever have the fish in total total darkness. It keeps them from being startled when the lights come on. The 2nd is a day light and comes on during the hours of the day to simulate a more brighter ambient which would indicate day time. It shuts off with a timer with the aquarium lights come on. It is I think only 12 or 13 watts. Maybe you already have some ambient light, I don't know, but at the very least everyone should consider to have something like that. Of course, circumstances differ. I don't advise it in a room such as a bedroom. On the other hand, there's always a question as to why fish jump. One time my wife was in the room when one just plopped out of the tank and flopped around on the floor. She was shocked to say the least. She did manage to get it back into the tank. Bless her soul! But why? and why then? It remains a mystery to us.
