Never even thought or heard of this idea, I enjoy having my tank lights on, and I have plants around the tank for they should be on for a little bit but what I might try and do is maybe set them for late at night when I’m sleeping, and I’ll drop food in as they are going to turn on. That way when the lights are on there’s no movement around the tank and then when I’m moving around the tank when they are normally scared the lights will be off!
Thanks for the tip, I’ll most certainly give this a shot!
Timers are a good way to do this
