Here couple of shots I took recently.
Male Heros Efasciatus like to play with one of females Heros Apendiculatus (I think it's still valid name, even though I call all 3 H. Efasciatus) housed with him in 6 ft tank.
One week he is with smaller girl, another with larger. Player!
I have them around 4 years, and they sized: male 10", female 10.5" and smaller female 9"
