this might be kind of silly question but I just want to make sure I’m not stressing out my Betta fish. So I work your standard 8-5 workday and since I like to see my fish I have the light set to turn on at 3:30pm and turn off at 10:15pm the tank gets very little natural light during the day. It’s pretty dark room but not pitch black or anything. I guess my question is I’m not sure how many hours of total darkness they need a day and if it’s okay to actually even slowly nudge the ‘on’ schedule further to something like 5pm to midnight or something? I’m kind of a night owl and the tank is in my room. I cover the front of it with a blanket at night so that light from TV or lamps doesn’t mess with his night/day perception, I hope. Is this alright? Or should I readjust? Thank you!
