Tor regarding your setup and stock selection I would like to say for me is about perfect. The way you have setup the tank is amazingly natural and I personally think eartheaters, severum and discus are my favourite fish. I have watched your video about 10 times!
I hope to have something similar one day.
Regarding your lighting, I guess its each to their own but "dead spots" as you call them are a normal occurance in nature and in my mind make the setup even more realistic.
All In all perfect. More videos please, especially of those altifrons!
