In reference to a recent post by dankfishtanks called something like Sub Adult Vieja ID, I referenced the Aqualog book (and cichlidae.com) before venturing what I suspected was a decent answer,
In Aqualog there are 4 photos of hartwegii, a juvie, a young male, a mature male, and a female.
Info states where it is found, (counties, river system)and estimated size.
