Geophagus iporangensis is part of the braziliensus complex, so the differences are very minor.
Looks like it's been poorly taken care of, so you may get a better idea after you've given it TLC.
They do appreciate cooler waters than many tropicals, and although they don't require cool downs like Gymnos, they are from more temperate areas of Brazil.
I've had braziliensus spawn in my ponds when temps were on in the 60sF.
