Stupid question: Left Blue Lights on Late Into the Night

[splix]

Just checking consensus here. I was doing a little bit of work on the tank late at night and my lights were about to go out. I forced them to stay on until I finished up. Of course what happened was I forgot to turn them off when I was done.
My blue only lights, not moon lights, my full blue side of the lights were on until around 1:30am. Typically they shut off around 9:30-10pm.
I noticed some fish still awake and swimming around when I rushed downstairs to turn them off at 1:30.

Should I be concerned? I'm thinking about doing a no lights day today for the tank, but I dont want to do that if it's just going to confuse the light cycles of everything even more.

That would not concern me. :-)

I've left my entire system running for a whole night ( a few times overriding my controller working in the tank) and no worries/iasues at all.. I wouldn't change a thing Def advise against leaving the lights off a full 24 hrs due to a linger photo period of a few hours ..
