Stocking A 90 Gallon

[jwolf004]

Hi Fish Forums! This is my first post and I'm excited to get feedback! 

 

 
I am restocking my 90 Gallon aquarium and need some advice on compatibility and overstocking. I am running 2 canister filters on my 90 and have 6 Silver Dollars. I want to have a somewhat peaceful stocking and have thrown a few ideas around to add to my tank. 
 
These are some ideas I have 
 
First Choice
- 1 Chocolate Cichlid 
- 6 Silver Dollars 
- 6 Rainbow Fish (some sort of schooling fish)
- 1 Peacock Eel
 
Second Choice
-1 Severum
-1 Acara
-6 Silver Dollars
-6 Rainbow Fish (some sort of schooling fish)
-1 Peacock Eel
 
Are either of these compatible with a 90 gallon aquarium? Any suggestions on moving forward with these stockings?

Im thinking 90 gals is 5ft tank? What about a pair of severum or acaras instead of individual ones.
