Do any of your fish panic at lights out?

My old tank I had, when I turned the lights off, my yellow tang went crazy!.. It was fun to watch though!

 

Have you noticed any empty PBR cans by the aquarium? algae encrusted cars around the mandarins area?

 

I feel like I just missed something happen before lights out that freaked them out. The clowns didn't even flinch last night when the lights went out.

 

My clowns dont panic they just go to a corner and sit there all night, my file fish sleeps head down, rest of fish just go into caves. All the inverts and starfish love it when its dark. I have pcs, halides and moon lights. I slowly shut them off in hour intervials.

 

Usually mine do too =) I also stagger my lights by an hour bc I assumed originally it would lessen the shock of having the sun suddenly go dark every night.
