Hello! I have many questions about my 1 month old 20g freshwater tank. Currently, I have 1 angelfish, 1 hatchetfish, 4 neon tetras, and 4 cory catfish. I have recently started to get into plants which I recently purchased a small Amazon Swords with my gravel substrate. I give it root tabs but after I get some more plants, I am going to move to liquid fertilizers and maybe add CO2. What gravel/floating plants does everyone recommend? What fertilizer if any? In a couple months, when I get back from a long vacation, I am planning on removing the Hatchet and Angelfish. I want to add 2 more Corys, 4 more Tetras and a Paradise Fish (preferably female for their temperment). The tank water is: PH~7.6, Temperature- 78-80F, 0 nitrates and nitrites. If tetras dont get along with paradise fish what others can I put in a 20g that get along with corys as well? I have a filter attached to the back of the tank creating a small waterfall. I recently added airstones as its increasing the temperature and too much movement at the top, as I read Paradise Fish like slow moving water. What food do you recommend for Paradise Fish as I currently have flakes, dried bloodworms and sinking pellets for my corys? Do I need a lid on the tank if I add the 3 species of fish? I am going to soon add a light that runs 24/7 with sunrise and sunset (pictures below). I would love to hear everyones thoughts and opinions. Thank you.
Ps. The pictures of the 3 plants Below are what I was thinking of adding (hornwort, moss balls and one more)
