Uaru amphiacanthoides.
I wouldn't put jurupari's in with brasiliensis or heckelii, both are too aggressive for them. I go with Geophagus altifrons instead, they get larger and have are more assertive. I would think they can hang with the others.
Remember brasiliensis and heckelli will form pairs, might have to remove some once they do even with that tank size. I'd drop the number of brasiliensis and increase the group of altifrons.
Also slip the bolivians. They would do fine with altifrons or juruparis, but deffinately not with the brasiliensis.
