Wish I could help, Im in the same boat. Funny I just got a 75 and I been thinking of adding pretty much exactly what you mentioned ha ha. Hope someone with more expeiecne chimes in as I never had any of those listed fish yet besides Pictus cats.
For stock we have similar taste, so this is what im thinking.
3 Butterflyfish (Should get floating plants, unsure if its a must or not or might even grow pothos plants on top so the roots can give them shelter)
2 Severums (Bright Red Pair) or another kind of center piece fish
2 Delhezi or 2 Senegals (I read Delhezi gets little bigger, but more laid back compared to senegals that are more active, and stay smaller)
5-6 Cory Catfish (if I can find some small enough yet big enough to not fall prey to the Bichirs) OR 2-3 Pictus Cats or a cat of more color
Catfish I been thinking of corey catfish, but unsure which ones would be small enough to have 5-6 of them yet big enough to not get eaten by the Bichirs.
I think this is pretty much maxed out for me, maybeI might add some smaller dither fish just to keep the middle of the tank more busy. I really wanted to add elephant nose fish (which is technically a type of knifefish if not mistaken), but I think bottom of the tank is getting to crowded already. Also I hear mixed opinions on if elephant nose should be housed alone or in a group. Alone maybe I could take that chance but unsure.
Good luck, if you have set up your tank already let me know what you stocked with it for ideas.
