Looks like a male.
I have been doing lots of reading about GBR because I want to keep them in a 135 gallon im going to be seting up and I found this article - and according to this article that GBR would be a female -- http://www.aquaticcommunity.com/cichlid/germanblueram.php if you scroll down that page, it shows male and female and how to tell them apart.. So, I guess im curious as to if they are wrong about only females having black on the pectoral fins :eek5: because personally it looks to me as if there is black on the pectoral fins and that black spot has some blue sheen on it around the bottom edges.
