Hybrid Livebearers

well, i hope it will work, ill probly change my 17 gallon to brackish for the hybridization attempt, once i get rid of my female kribensis that is
 
well, they are technically brackish species. but oldman47 says he keeps his mollies in freshwater because he has hard water with a high ph, and since i have the same, i might not do any salt in the tank, and keep them in the community tank, not the babies though.
 
Can i ask if you use a small breeding case thing how long before you can release them into the whole tank without getting eaten ?
 
I have done this before. It was an accident, and there was only 1 surviving fry. The fish grew to about and inch and a half, the body was all white, except for patches of orange and black, it has lyretail features, while it's body was more of a guppy shape. She bred with a regular molly, but I was gone when she dropped. According to my younger brother, all they fry were dead. I sold her a couple years back. I would try and locate a picture of her, but I have no idea what photobucket account I used. I'm sure they are here on the forums somewhere.
 
well, i got some male guppies now, and im pretty sure my molly females are (or at least were) virgins, so ill see how it goes now, i hope i can get it to work, then ill probably do more picky crosses, and maybe see the fertility of the fry.
 
It comes down to latin names. The names adhere to a system, one can tell how closely two species are related by there names. As far as we are concerned only genus and species names are used. Though there are exceptions, in order for two species to hybridize sucessfully they must have the same genus name.

platy-Xiphphorus variatus
swordtail-Xiphophorus Helleri
molly- Poecilia sphenops
guppy- Poecilia reticulata

Guppy x Platy will not work. You can attempt it, but honestly you are wasting your time. Its about as possible as crossing a dog and cat. Also just because they have the same genus name does not mean they can hybridize. Some may only be able to hybridize artificially, other may have genetic issues. It usually comes down to number of chromosomes, guppies and mollies have 23 + X &Y chromosomes. Platies I believe have an extra chromosome. These are our genetic blueprints, if they don't line up they cannot combine into an new individual.

If you found some pics please link them.

Thanks! I guess I better go separate my Guppies and Mollies...lol
 
im pretty sure my male guppy has bred with my silver lyretail molly virgin, now just to wait to make sure. i hope all goes well. and i hope they look goood. i just need to get my breeder trap back from a friend now lol
 
me too, i hope its a challange, im getting bored of just cleaning and feeding, i need a challenge!
 
i am a failure, after a few months of nothing, i decided to release my male mollies into the tank. so now i need new virgin mollies, and the mollies werent getting pregnant anyway, not that i noticed anyway. maybe one day ill dedicate a 10 gallon to this experiment, so maybe the babies will survive.

Dont Worry my guppy did the same thing and then got killed by my cichlids. Hope u get lucky next time!:)
 
guppy x platy is possible but rare. i have had it happen but they got eaten. i am sure because i put one of my 4 month old female that had no contact with developed males with my guppy male they mated and she had fry. they have a different amount of chromosones 23 for guppy 24 for platy so just dont expect it its possible.
