Definitely female based on signature of a lot of red and dark band on the dorsal fin. You got a good deal because female Festae is more colorful than male. There is sexual dimorphism in Festae.
Man, you don't want that. It's a male. Ugly one too. Tell me how much you want for him and ship him to me... I'll take him off your hands. LOL... j/k, of course! Gorgeous female!
