kevincanada Posted December 26, 2022 Share Posted December 26, 2022 I have been selectively breeding the late maturing and much larger swordtails. after a couple of years now i notice that at full size, even the females have a tiny nub of a sword on the tail. perhaps the small ones at the pet stores have this feature too but we just dont notice it. just thought i'd share with the group. cheers from freezing ottawa! 5 1 Link to comment Share on other sites More sharing options...

PineSong Posted December 28, 2022 Share Posted December 28, 2022 Wow, that's super interesting. I just started breeding swordtails a few months ago so I will keep my eyes peeled for this kind of variation. Great color on your fish--and your male's sword is nice and dramatic. My first batch of offspring are just now starting to grow their swords. I only kept three males from that batch and they are all developing at a different pace. 1 Link to comment Share on other sites More sharing options...
Patrick_G Posted December 28, 2022 Share Posted December 28, 2022 That’s interesting, I’d keep breeding that line if I were you. The color is incredible and the female’s little sword nub sounds really cool. On a side note, female Swords can transition to male if conditions are right so maybe your are primed for a change. 1 Link to comment Share on other sites More sharing options...
DaniV Posted December 28, 2022 Share Posted December 28, 2022 Absolutely gorgeous! My 2 female swordtails don't have any signs of stubs, so maybe that's due to the breeding? Keep it up~! 1 Link to comment Share on other sites More sharing options...
kevincanada Posted December 28, 2022 Author Share Posted December 28, 2022 i got the idea to breed for large size from Cory's interview with greg sage. these males are almost 7 inches long with tail and the females are about 5 inches or so, i think. what i did was remove all the early sword bearing males. then the ones that i thought were female keep growing and then after several months start to show sword etc. not sure if they'd be viable commercially because of the long growout period and the giant size but i really like them and find them spectacular. thanks for all the kind comments. cheers. 1 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted December 28, 2022 Share Posted December 28, 2022 The ones I have from @Minanora are similar. The bottom fin tail ray is definitely pronounced. 1 Link to comment Share on other sites More sharing options...
