Oh I forgot to mention. If you want some specific advice, a good description of your substrate, fertilizer routine and lighting (both spectrum and WPG are useful) would go a long way in helping people to give suggestions of what to put in your tank.
For example, I only suggested plants like java fern, java moss and anubias because they are basically invincible and are a good and safe bet in any aquarium. If I knew your lighting situation and fertilizers used and your substrate I could suggest some more beautiful options and plants that might suit your current plant themes.
