This is not true, I've seen males and females with the red line on the dorsal fins. I've also seen males that have barely ANY red if at all in the dorsal fin. The 100% foolproof way to sex one is venting, there are always exceptions with sexing a fish by looks. Some can look like males but be females and females look like males (Example is my female Convict x HRP, she has trailers on her anal and dorsal fins). With the EBJD, they often times look the same IME. The biggest concern with these fish is when small is not knowing if they'll be deformed or not. Often times that isn't known until they reach a certain size.
