Hi ya iceterran...
Nice set up! Looks pretty new. :)
The hygro will take over half that tank in no time. ;) :) The blyxa might have a bit of a hard time with the floating veggitation ya have in there at the moment. They really need a bit of light and the dense floating carpet you have will rob them of that..
I would personally put a background on the back an sides. Helps with shadows bouncing of the back wall and make the discus feel more secure in their enviroment.
