I'm going to be buying a Fluval roma 240 on monday and it's mainly going to be for apistogramma so I want a theme based on them but I'm unsure on what substrate and plants to use. I know I want the background to be a riccia net and I want a mantanzi branch with each arm covered in java moss, I was thinking about using terracotta pots but I'm not too keen anymore so I think I'm going to be using flat stone and blended rocks for caves. The tank is 2cm under 4ft if anyone isn't sure what tank it is. I will let it cycle for about 6 weeks before adding anything so hopefully the plants will grow a bit by then too. I have a few questions so here they are. Would I be able to keep a successful 3 female to 1 male harem spawning frequently or is it risky keeping 3 females in a 4ft tank as I understand 1 female takes 1.5/3ft of territory? I want floating plants to cut out a bit of the light and to fill the top area but is there any themed plants that will grow well under little light? Are pencil fish still the favorite for dither fish or is there any less harmful fish out there? What would be the best bulbs to use? My pH is (usually) 6.6 but it can creep a bit higher during water changes but I'm not too worried about that. Another thing I'm not too sure on is if I'm going to need CO2 for the plants or not.
