I have a 11in 18 month old RedTex female. Tex/Festae hybrid. 44 years and hundreds of fish in my hobby life. Hands down the meanest fish I have ever owned. Killed a male Jag when she was 3ins long! A complete psycho goon, but such a pretty girl!

Every cichlid is different personality wise. You can have the most sadistic psychopathic angelfish and the most sweet innocent dovii. I know this is silly, but it happens.
From my experience, I think the grammodes is the winner. I've tried breeding them before, never worked. It always ended with one dominant male grammodes. I even tried adding dithers, it never worked.
I think the dovii is a close second. Apex predator. Every specimen I've owned battered anything living with it, although they were all males. Females of this species are mild, which is strange. Grammodes and Haitiensis male or female regardless are machines!
