The differences in the females are much easier to spot than in the males. Female nijseni have a large spot in the caudal peduncle. Female pandurinis have a thin oval spot over the central body spot--almost like a key hole. The bottom of the oval spot runs into a huge spot that covers the under-side of the fish. It looks almost like an upside down saddle on the fish. In addition, I have seen some females have the big bottom spot/saddle extend into the throat area. Thanks to Lisa Wrischnik who helped helped me figure which are female pandurinis from a mixed tank of apistos the first time I saw them at a local store. I thought this might be useful, since females will often pick the "right" males when given the choice. ______________________________________________________
