I Don't believe Danios do well in the temperature suggested to keep discus. With my 180 Gal Discus community tank I will be stocking with

Bleeding Heart Tetra
Red Cardinal Tetra
Corydora Sterbai
Discus

How about rummynose tetras? If you had a huge school of them they would look crazy cool in a tank that size. They school more tightly than any other fish I know of. And even though they stay small I think they would be ok with smaller Geos - Geos aren't very predatory.

You should do at least 20+ corys in a tank that big (Sterbai are best temp wise). I think you could do 30-40 easily.

You could also look into getting a school of Elephantnose fish or baby whales. I think they could do well in a tank like that (if you are willing to feed them the frozen food they require). They are really amazing fish, that more serious hobbyist should keep, imo.

+1 not many fish like the temps Discus like. I was gonna say Cardinal, Rummy Nose, or Sterbai. For a top swimmer I may try a Silver Arowana, not really sure how compatible they are with Discus, need more research.

Here is a video of the big tank with a school of ENs - in the video they are kept with loaches, but I wouldn't recommend that - corys seem to be ok, if you train the ENs to eat from a blackworm cone (because the corys mostly stay at the bottom), but loaches will eat from the surface, and faster than ENs can.

Also look into Uaru - they are big cichlids, with great personality, extremely un-predatory (is that a word?), and they like discus temps. Love them!
