I can’t find the info I read from Duane on forehead profile for sexing Central Americans, but I’m not sure if it mentioned labiatus…
Well, I have half a dozen aggressive American species, all fairly young, and I recently added shredded beef heart to the diet. After a few days, several species started showing courtship behavior (green terrors, motaguense, and a carpintis courting a red devil. The carpintis is a bit larger, and dominates the tank, but doesn’t bully. (They’re all in the 4.5 to 5.5 inch range.) The carpintis has tolerated that red devil in its area, for months now. My devils all have a mild “hump”, caused by an indentation between nose and upper head, and I can’t distinguish sex among them. And judging by the forehead, I wonder if the carpintis is female.
(I included a picture of a second devil for another forehead profile example.)
