Honestly, I dig the planted tanks and community tanks, but something else I would do would be an assortment of eels, Bichir tank, Geophagus, some Larger Catfish species, Dojo Loaches and some cold water fish (They are addorable), and if you want something not a lot of people do, a Giant Pea Puffer tank. My personal fav is the pea puffers just because they are adorable, and they seem to have a lot of personality. I would DEFINETLY not Discus because of the water parameters; always need pristine water. Good luck!
