Viewing Your Aquarium With Lights Off

[CavalierReef]

If this is discussed elsewhere on the site, I apologize. I thought this would be an easy search and that has proven to not be the case. I simply want to see what's happening in my aquarium at say 2 AM. Whose roaming around, who is attacking whom, etc. I've read somewhere that a red lens is effective. Is that the case? Any recommendations are appreciated. Thank you.

I use my iPhone flashlight .
And can see all life that’s not out during the day .

A red flashlight can be used to see your tank without disturbing the inhabitants

I use a PVS-14.

I thinks it's really cool watching the tank with lights off... Checking out all the pods roaming around, and the fish sleeping in their caves. I just use my iphone flashlight...
