If you want some ideas for your "wild amazon" tank, look no further than my clicky's in my sig. I am currently experimenting with a variety of plants, which explains the jungle look in the first pic.
I agree with Zagz in regard to discuss. They are not the ideal "community" fish in that their care is very involved (constant PWC
's). They can be housed with a limited number of other species though not as many as a full community.
I would suggest posting your thoughts in the General Discussion forum with the title "I want Discus" or something similar. That will bring our Discus folks to you.
