there are some mollies, platy's and swordtails that, even after being sexually mature will appear to have "changed sexes". these fish that "cross over" are considered sterile. It is unknown why this phenomenon occurs.

Exactly what we have noted. Of course two months is a normal range for gonopodium development. But mine developed its gonopodium at nine months of age and it was already a large fish when this happened.
