Help Identify My Geo's

[Leongy]

Hello guys, just got three of these specimens. i know for sure they're geophagus. just not sure what kind they are. i'm rather curious as to which exactly are they.

the three of them are around an inch and a half long.
would appreciate if anyone can help identify these! (ignore the bolivian rams in the background)

thank you for your replies! i'm glad i got Balzanii. its a pleasant surprise because i was expecting altifrons or heckelli for that price instead. got them for $1.20 each.
