Hi everyone, my name is Eric and I am looking for some help. Ive kept fish my entire life (I'm 45 currently) and something quite extraordinary has occurred . I have had a successful mating of a Swordtail and a Sailfin Molly. I know this is supposed to be impossible but it happened. Here is a video of one of the male offspring http://youtu.be/7HVsEnW_Mhk So I was wondering 1 Has anyone else done this ? 2 Where can I get one of the offspring DNA tested to prove this seemingly impossible mating occurred. Some of the female offspring are already looking pregnant so these fish seem to be breeding . Thanks for taking the time to read my post and I look forward to talking fish with everyone here .
