Jurupari and surinamensis (and the similar species) all get 10"+, I think you will find your tank is very overstocked with all these large cichlids in addition to those other fish. The ones I recommended, the redhead Tapajos, only get to 5-6". However, with all those other fish in the tank I did not take into account, I think it would be too many fish. I would pick your favorite of either the Uaru or the geophagus, and do one or the other. Either pair of Uaru, or group of smaller geophagus species.
