So ive just added clowns to my new tank this week. Overall so far they seem to be doing okay, however Ive noticed they are 10x more active at night then during the day, even with the tank lights off they dont typically leave their corner. But come night time when all the lights go out and the tank is in complete darkness suddenly they become little adventurers and want to explore the tank -- even seems like one of them is having fun getting blown around by the powerhead flow. My tank parameters are safe. Are they simply too timid and not fully adjusted to the tank yet or do i have a pair of oddball nocturnal clownfish? Thanks for any input, im new to this hobby.
