Argyrostictus are quite aggressive both externally and conspecifically. I'd recommend a large setup with a large number of individuals to begin with. Please note I have no personal experience with them.
sp. "Pindare" can be quite tedious and should be kept in ideal water conditions as they're prone to bacterial infections.
Treat the Areoes as an altifrons, very similiar species (I've even read it's an alternate name for G. altifrons "Tocantins"). Both will be quite hardy but need large setups.
Satanoperca maripitensis need ideal water conditions otherwise they will develop skin lesions on the forehead similiar to HITH. This doesn't mean bi-daily water changes to keep Nitrates down, it means making sure they're kept in a soft, low pH and low TDS/conductivity setup. While these lesions will happen to most Eartheaters if kept for long periods of time in hard water, Satanoperca are especially prone to it.
Other than that, the usual. Fine sand substrate, variety of crushed/1mm high quality sinking pellets such as New Life Spectrum, driftwood and rocks for cover, subdued lighting and high capacity filtration with lower flow rates. Sounds like you've got the 4+ per species covered.
Any info on your tanks, set up sizes etc...? I am really partial to the Satanoperca Mapiritensis owning a group myself. Would love to trade experiences with a follow MFK'er.
