If you want to grow grasses in your tanks, you'll need a very bright light (T5-HO or more), nutrient-rich substrate, and possibly C02. Those things can be so difficult, especially the foreground grasses. Although again, I wouldn't really recommend the betta community setup. You will inevitably have losses, no matter how peaceful it is at times. The only way to try a betta community without losses is with other betta species such as betta pugnax etc. Many of the mouthbreeding bettas can be kept together but they also get very large and need tanks that are at a minimum 20 gal long.
