Ammonia/Nitrites ~0. Nitrates ~5 ppm. Temperature is around 76. Light I try to not have on too long as I read they can be sensitive to bright light so only a few hours a day for my plants but they behave similarly when the lights are off..

I recently added 5 cardinal tetras to my newly cycled planted 20 gallon aquarium. It has been about a week and they kind of just hide behind the plants most of the time and dont do much swimming or schooling. I have checked water parameters and everything is safe. Any suggestions? I am considering adding 3-5 more tetras but did not want to overstock the tank too quickly! Thanks!

[Cleaning Surfaces after Cycling]

Hi! I’m new to the hobby and recently started a 20 gal planted tank that is almost completely cycled (ammonia and nitrite at 0 with some nitrates) I was wondering if/when I am supposed to clean surfaces (tank/filter/decorations/substrate) of algae before introducing fish to the aquarium. Concerned about killing all of the good bacteria that has been built up. Any advice/suggestions would be great
