Nature finds a way.
George Barlow tells about a Jack Dempsey female that laid fertilized eggs. I guess She was the only fish in the enclosure. IIRC it was in his book " Cichlids, nature's grand experiment "

(copied from the other thread)
Jay Stauffer mentioned this in his program down at the OCA Extravaganza.
I believe I have read elsewhere that the fish do not change sexes, they just develop both male and female reproduction ability. IIRC, it is called gynandromorphism, similar to hermaphroditism.
