Tonight, I felt great to have a chance talking to a new friend named Ken whereas in our conversation, I found out that Ken by chance did a magical thing - discovered kings-lyre trait from his swordtail cross breed. What Ken did is he crossed a Rio Otapa male swordtail (wild type, black markings) to an Albino high fin red mother [P], and the result turned out more than surprise when 6 kings-lyre males appeared in the offspring [F1] out of about total 20. So, the ratio of kings-lyre male in his F1 is about 25%. Plus, he reported to have 2 females, 1 with long lower sword as the regular male swordtail, the other (a high fin female) has a short sword. Isn't that interesting? Unfortunately, the parents didn't survive long enough to carry more births. And the long sword female had died from bacterial infection while being isolating for delivery. Those pictures below provided by Ken. The first 4 pictures are from a kings-lyre male, and the picture #5 is the female sibling with a long lower sword. I know that some of you would ask what is kings-lyre swordtail and may find it confused if having to tell the different between regular lyre swordtail and kings-lyretail. This is what I learned from Rainer about kings-lyre in comparison to regular lyre swordtail:
- KL has uneven pair of sword and the upper sword is much shorter than the bottom sword. - All fins are elongated as in regular lyre, except the gonopodium (sex organ) of the male swordtail is short, thus letting him be breedable in a very natural way. - Also, Rainer suggested that female swordtail born to a king-lyre may has bottom sword protruding from its tail. For further detail of his observation, please refer to Rainer's website. I also added some pictures below to help you with a general idea of how a kings-lyre should look like.
