Wow 😮 that sounds like it could be amazing!!
If you have any sense go with larger discus fish after you have the scape put together. Maybe start with all the dither fish and other community fish before the discus to save a quarantine tank.
Big discus and good Maintanance regime beautifully planted and you have the dream!!!
It could be speactular !
I’m more than a little jealous at the thoughts of it. Post plenty of photos
