Even though it's a very big tank, I still say no.
Flowerhorns get massive, about a foot long, and although cute when they are little, they are highly aggressive and territorial and will kill all those peaceful to semi-aggressive fish.
What do you mean by "a bunch" of bolivian rams? If you have too many there could be some pairs and it could get kinda nasty between them.
Not sure about the geophagus.
I don't think the clown loach should be in there, only because they get a foot long and need a school of five IMO
. But that's just me.
Just my 2 cents.
