Hello, have just set up my first tank, had it fishless for while then introduced fish on saturday. The tank sits in lounge so natural light cycle is light, but fairly glum during day (as only light is door to balcony), artificial light (ie lightbulb) in evening til about 11:30pm then darkness til 7am. Was wondering how often i should have light on that is in hood of tank. Does too much upset fish? Does too much darkness upset them? And are these blue nightlights ok for fish's wellbeing?
Also, how often do you feed fish? Says on packet 2-3 times a day, man in shop who seemed to be very knowledgeable said only a few flakes every 2 days.
And finally! How do you change water? If i change it with new water, won't temperature of tank go down? Is temporary reduction by couple of degrees dangerous? And these drops you put in to get rid of tap water chemicals-do they work instantly, or do you have to let water sit for a while before adding to tank?
Sorry so many questions, and sorry if i am going over old ground!
