so, so one of the things I get to see with my morning caffeine, is the "shift change", as I'm at my tanks, at or just before the early morning 1st lights begin to turn on, and amongst all groups of fish there are different "shifts" the hobby often used nocturnal only, as not a "day" fish... but I get to watch my fish waking up... the nocturnals are active before the lights come on, obviously, but some fish are early risers and are active as soon as the lights begin to come on, while some fish seem to regularly sleep in, and don't become active for several hours after the main light comes on, then often the early risers are less active as the main light comes on... anyone else noticed the varied activity levels of their fish??? there seems to be more to it, than just day and night active fish...
