Crossing of sjoestedti with Fp. spoorenbergi by a friend in SA yielded a very interesting assortment of fish that looked like neither fish... at least as far as the males were concerned. One couldn't tell the hybrid females from the real deals though...
That said, hybridization is possible and the eggs may well survive to hatch. I do think that your mature SJO would most likely see the GAR as food rather than mates.
