Dec 13, 2008 - The common Black Molly is a livebearing fish that is fairly easy to breed
Pictured is the black molly. These livebearers like some aquarium salt in the water and will give lots of fish babies. Be responsible and only breed them if you have a plan for what to do with all the fry.
Black Molly - Swordtail Half Breed - tropical fish tank. I gather they call that a cross-breed Molly/Swordtail. Here is an update on OBI, as we named him (Orange Black kenobI). This is a mix breed. Half Black Molly and half Tropical Swordtail fish. Here was original video of the Black Molly-Sowrdtail fry:
In the first video posted on Christmas 2012, some commented that this was biologically not possible. Mollies en Swordtails cannot breed with each other. Then again, others said Swordtails can breed with Black Mollies. I think that this is, proof in the pudding - proof in the aquarium - a Black Molly and a Swordtail can breed and produce fry or baby fish!
"can mollies and platys or swordtails breed?" See forum post:

The common Black Molly is a livebearing fish that is fairly easy to breed. I had a 20 gal. tank set up for my breeding mollies and started with about 4 of them. After a couple years, I was giving them away and selling to local aquarium shops, I had so many. There was a constant supply of breeding mollies and young, growing fish in one tank (photo below). They are a fun fish to watch and will happily breed if you give them the right conditions. Let's find out how.I've been breeding Mollies, Swordtails, and Guppies since I was about 12. I've tried breeding betta fish, but the babies are so small and fragile that they always die. I took a long break from livebearers and had some tetras and angelfish. I had a Dalmation Molly that had 14 babies and only one made it to this day. The mom and dad got eaten and I moved the baby one to its own tank immediately. I just bought him an all black girl and she just had 9 babies two days ago! Black babies are the absolute cutest! The 2 adults never picked on them but I moved the parents to a larger tank and bought 2 gold dust mollies and a male swordtail. Breeding this fish is the coolest thing in the world. They are so adorable and is a hobby of mine.The Black Molly is easy to keep and easy to breed. They will eat all kinds of food including flakes and algae. I suggest to give your Mollies added nutrition from the vegetable supplements. These fish are social and very active fish. With a proper diet they are a great addition to any community tank.A 20 gallon aquarium is a good minimum size for this fish. The larger the tank, the more stable the water. Filtration that does not disturb the surface is ideal as the black molly enjoys skimming the surface with its mouth, looking for food to eat. A heater is also required to keep the water at an ideal temperature. Tankmates should be of the non aggressive type, and bear in mind that the fish can be a prolific breeder so don't be surprised if you wake up one day and see little black dots swimming about.
