There are many nocturnal fish (eels, catfish, plecos, loaches, knifefish...)
I was wondering which lighting is better for viewing the fish at night, when they are most active!


I know blue light simulates moonlight and is more natural looking (sunset/dusk appearance).
But I also heard that fish cannot see red light, thus red is more effective.


Anyone know which is Truly better?
