Neptune is in a 2.5G tank with an aquarium light which is switched on the whole time(except at night), but my gripe is that we are constrained to keep the adjacent lights in the room switched on as well, lest he see his own reflection in the tank walls and start flaring.
I've observed this behavior the moments the lights in the room are shut and only the aquarium light is on. My wife jokes that with the kind of continuous flaring he does, his gills are soon gonna fall off
But seriously, how bad is flaring and does it stress them out? I can't move tank to any place else, so is there a way out of this conundrum?
