Does anyone here have experience with this? More than six months ago, I set up several tanks to breed male guppies with female mollies, and male picta livebearers with female guppies and endlers. I have always been fascinated by hybrid fish, and my goal was to breed some for a display tank. Unfortunately I have had no success. I do observe mating behavior from both pairings, but there are no fry. The pictas are especially voracious. They breed the female guppies and endlers constantly, but still no success. And it's not that the fry are being lost. The females just aren't pregnant. Their gravid spots and belly size never change. I did copious research prior to setting this project up, and it seemed like it is possible to get hybrid fry from both of these species pairings. I've seen pictures and videos of supposed molly/guppy hybrids that look quite convincing. And as for the pictas, a site called livefins.com sells what they claim are picta x endler hybrids. In addition, a breeder called Lotsoffish has a video on youtube of picta x guppy hybrids. I've also seen some threads around from people claiming to have done it. I don't doubt that it can be done, but is the chance of it working just extremely rare? I thought for sure I would've had some form of success by now, and lately I've been considering giving up and doing something else. Is it just completely by chance that certain pairings are successful, like winning a genetic lottery? Should I try getting different breeding stock, or just keep waiting?
