Crossbreeding; Guppies, Swordtail, and platies oh my
 
Hi! In one of my tanks I have dwarf panda guppies and Kohaku (koi) swordtails (among other non-livebearers). In another tank, I have just some regular guppies (also among other non-livebearers). I have kept the regular guppies out of the panda guppy tank so that I could make sure any fry in the panda guppy tank were just panda guppies, not mixed up with the regular guppies. I have not worried about the swordtails and the panda guppies crossbreeding because I read somewhere that wouldn't happen between these two.

I have more fish arriving tomorrow. I had ordered 8 more Kohaku swordtails (look like my avatar), but they are low on inventory and are instead sending a few swordtails but substituting several honeybee platies. Do I now need to worry about crossbreeding between the platies and either the guppies or swordtails?

Good afternoon
I am a livebearer person too. You dont have to worry about your guppies, but your platy's will breed with your swordtails, or vise versa. So if you want to keep the breeds true, you should have at least 2 different tanks to house them. 3 tanks would be ideal. I keep my guppy's and platys together. I have a tank for males and one for females. I am working on guppy strains, so the girls only see their fellas for very short times.....lol

Thank you so much! In my tank with regular guppies, there are no swordtails, so I will put the platies in that tank when they come. I am not qualified to work on developing a "Granberry Guppy". :) But I do have fun seeing what the fry look like, keeping some for myself, and giving the LFS whatever they will take.

just have to say, I breed platies and swordtails, and mixbreeds. The fish in your avitar is a female platy, not a swordtail

Yes, I know it is now. I changed my avatar since I posted that. :) It was a Kohaku swordtail. You can see the picture in my albums.

Crossing platies and swordtails causes hybrid breakdown in the F2 generation. They will develop extensive melanoma when exposed to UV light. They will crossbreed readily, so having said this it may be best to keep the two species separate.
