Do you have any light on your tank at night?

I have a small Red/Blue clip LED light I have on my zoas in back corner if I leave it on ALL the fish gather in that corner after lights out.

Normally complete darkness except random leds on cable box, computer ect

My lights have a separate violet/UV channel that I keep at 3% for the night, no specific moon function.
When I get AI Primes for my 2nd tank I'll be running their lunar interface with their Violet/UV channel.

I use the Tunze Multicontroller to contol the Tunze Stream pumps. The Multicontroller has a light sensor on it so it can tell when the lights are on or off and controls the pumps in accordance. The end of the light sensor has a small white LED that acts as a moonlight, and it follows some sort of moonlight schedule - sometimes it is quite bright, other times it is very dim. I have it pointed so it goes diagonally through the tank from the back right corner to the front middle. The fish don't gather around it, in fact they all disappear and go to bed when the T5s start to dim.

My lights (radions) are completely off at 10pm. All my equipment is housed under the stand and the wood skirt hides the equipment with lights (doser, Heater controller). I do have a window in the basement near the tank that provides some might early in the morning so the tank isn’t pitch black.

My refuge located behind my display lights up the whole garage dimly, DT is dark however there is light bleed, fishes sleep and this is the best time to feed the Bangaii and long nose hawk, the anthias and chromis eat as well.
