Genetic defect - Swordtail

York


20220123_002118.jpg
I've searched high and low and the only thing close to 3 tipped tail on a sword tail is a high fin, lyretail sword, the point are not as distinguished as this one. The batch of fry this guy came from all have weird traits (very long gonopodium) (multiple fins).
Anyone know anything about this? I was going to breed him with a female from the batch he came from and see if the offspring carry the same trait. That's if he can breed.
Any help would be great, thanks.

Oh, that's interesting! Maybe you have a new species variation on your hand!

This is one of his brothers.

Woah they are handsome:) If I had another tank, I'd really want to breed and see what happened.

Couldn't find any info but we used to call them Trident Lyre Tails .
Good looking fish and should be reproduceable. :cool:

He looks healthy, if you can, I would try to breed him, people will pay good money for rare varieties

I'd buy them, if I had space:)
Keep me posted, if I get a new tank, or something happens to the occupants of my tank, I would love some:)

It is not genetic, though it is technically reproducible. The abnormal extension grows from a spot on the tail where the fish had an injury or infection. When it heals up, it just keeps growing. More common in lyretail strain due to the normal genetic modifications of added fin growth. The elongate gonopodium of Lyretail Swords is what prevents them from breeding. BTW, your fish with the extra fin growth appears to be female, with the enlarged analfin of a Lyretail.

Hey this is great information, thank you so much!!!!
I will try and breed the enlarged male with some of the females I have regardless. I was always unsure about "his" sex, it's sisters have way larger fins; maybe because she is using energy to grow the damaged 3rd tail spike.
Appreciate you!!
