Hello, I have a small 10.5 gallon long tank, 35 inch length and 9 inch height, 8 inch width..Fishes: 1 red dwarf gourami, 5 neon tetras, 5 male guppies.. I have floating plants like Anacharis and Hornwort because its a bare bottom tank.Currently I have 15 watts of light which I think is too low and plants are fading colours. My questions: 1)Im planning to put around 35watts of light, Is that ok? 2)How many hours should I leave the lights on? My plan is from 11.30am to 9.30pm(10 hrs).Is that fine? 3)Do I need to add liquid fertilizer like "seachem flourish excel" or the fish waste itself is sufficient? Bcoz dwarf gourami poops a lot.. 4)Should I switch on air bubbles at night for oxygen since plants consume oxygen at night and there will be no oxygen for both plants and fishes right? Kindly help..thanks.
