apparently I cant edit my post. Meant to add they cant see red light as well so to them its almost dark.
The room it is in is very dark. I have an adjustable blue strip that was on the tank originally with the halides. I can do a minimal amount of blue and leave it on all night so I am not creeping along with a light. I can ramp it up to well lit if necessary but thought about this a few hours ago, been meaning to put it back on the tank anyway for some "moonlight" nights.
Think that will work? More consistent than a flashlight blinking on and off randomly.
