I agree the male looks similar to a freddy with more of a jag body shape, and the female looks very similar to a red tiger mota, however they also collected multiple races of motaguense so if either of these fish were mota's they'd have known. the guys on this trip were guys that really know their stuff. I agree that Rusty Wessel is one of the foremost experts when it comes to cichlids though he would never admit it. He's one hell of a guy and I might just have to see if I can get some F1 juves once he breeds the pair.
