Hi I have a freshwater aquarium fish question?

I just bought a 350 gallon aquarium. I was planning on getting about 10-15 discus fish, a datnoid, a fei feng, a couple of catfish and rainbow fish and 1 or 2 angle fish, 2 bichir, 2 severums, a firmouth cihlid, and a blood parrot, a little motoro stingray and a couple of angae eaters. Will they get along well. I know I will have to do alot of water changes, but I will do it. Will they be fine.
