Muppies And Gollies?

[Nathen]

Hi, sorry about this now
Im fairly up to date with livebearers as i have been keeping them for over 7 years now. Breeding stock for petstores nearby although one day, one of the staff asked "did i ever get a muppy or golly?" i was so confused so i asked questions got answers but im still not sure.
I know mollies, balloon mollies, swordtails, guppies, platy and endlers are related but only the endler and guppy are closely related. Ive seen breeds of endler guppies and i thought it was a great hybrid but anyway I have 3 40 gallon tanks, all heated all have some sunlight and a filter, subtrate used is river silt i buy at my local DIY store. I do a 25% water change every week and this grass like moss started to develop in my tanks, guppies love it and so to mollies The fish poop is broken down by the bacteria in my water and it is absorbed by elodea i have in my tank. Great plant by the way, quick growing and does not need extra vitamins and water plant food. great for fry aswell. I breed mollies and guppies by the way creating new colours but focusing on a long dorsal and round tail fin as ive read that its painful for guppies to have too long a tail so far ive tiger stripes which is lovely especially for breeders here in ireland. Down to business, Is it possible to hybridize guppys with mollies and get fertile fry sometimes? and can swordtails hybridize with mollies? i want to make it a project as there is a great demand for them by my petstore, i want to create a colourful breed of Muppy or golly to be able to breed and see what comes of them. any suggestions in getting them to breed?

P.S ive heard if there raised from fry in the same tanks and remove all female guppies and all male mollies the male guppies will accept them as mates? is this true also?

Thanks for reading
Nathen

All of those fish are loosely related but the subgroup we call Xiphophorus, which includes swordtails and platies are not close enough to the rest to cross with them but can cross with each other. Endlers and guppies cross way too easily with each other and so we try to keep them in separate tanks. I keep mine in separate rooms altogether. The remainder of the Poecilia are not well enough defined to know for certain which can cross with others. In general it is accepted that mollies and guppies can potentially cross, but I have kept both in the same tank as each other for over 45 years now and have never seen a cross result although guppy males are relentless in pursuing any and all females. Since mollies are of the genus Poecilia and swordtails are Xiphophorus, there is no way to cross them with success. Swordtail / platy sure, that is where all of the color variations of commercial swordtails comes from.
