I think you should get 20 exodons(bucked tooth tetras) hahah jk, the plan sounds good, and id let the tank cycle really good, discus breed fast, and they get super territorial, just saying!! good luck!
someone mentioned kenny here, i heard about him from simply discus (as in kenny cheung of daly city) i'm confused, is he a breeder or an importer? and does he have a free standing store or place where you can physically go to?
