This is a very unusual form of SJO. For decades only the Nigerian "Blue" form was known, despite Cameroon being mentioned in the original description. But in 1989, Horst Gressens of the DKG went to Cameroon and brought back the fish pictured here. The fish I took pictures of in 1997 are F1 from Gressens' fish, Dale Weber of the BAKA picked them up at the DKG auction and I got them from him. I passed them to Russ Feilzer when I moved from Las Angeles to Canada in 1990.
