Nice pair! I have a 10" F1 rio tumbes male thats an absolute stunner. Hes a bit of a wife beater but his female never grew past 4" for some reason and hes still putting on size. I think he wants to spawn and shes not ready so he ruffs her up. I separated the pair yesterday and hes by himself in the 150. Does your male constantly flair at his reflection and chase himself even when not in spawning mode? My male is constantly paying attention to his reflection and working himself up. Maybe i just grew out an overly agressive one.
