I would skip the plecos. I do like 20 mbuna in a 75G as this has been the correct level of overstocking, assuming you choose small, peaceful mbuna like yellow labs, rusties and acei. I would do mbuna only....skip haps, peacocks, other continents and plecos.
Four species with 1m:4f of each has good odds of success. Or you could do 1m:19f of a single species. or 1m:9f of two species.
Shoot for GPH of 10X so you should be OK with the FX4 unless you want reduncancy.
