My new Betta

[Smareers]

I've got this strange fin modification in my last breed of bettas. I've got a male and female whose lower fins are attached with their tail fins... is this a new tail mutant or do these already exist. I am attaching a pic of the male here.

Wow that is a beautiful picture of a beautiful betta, I am not sure about the tail, I was recently informed that our betta has a Unique tail as well, very cool

those are some gorgeous bettas. I love the blue, smareers

Beautiful fish!
Smareers, He's a rose tail which makes it have the "ruffled" look.
Lelei, your Betta looks like a Feather tail, which is like the rose, but more intense.
Hope this helps. :)

Thanks Jessicatm137. But I suppose the best thing to do is to breed the pair with this finnage and see how the next generation comes about :D

I heard Roses aren't good to breed, as you will get a lot of deformed fry. ( Bent backbones, things like that. )

Beautiful bettas!!!!!

rosetails are pretty, but not good for a breeding program ;p am not sure if it does cause spinal deformities but i know it causes scale deformities. pretty fish, and sometimes the anal and caudal fin do fuse together, some fish miss there ventral fins entirely o.o

lelei's betta's fins are just nipped up.

as for the OP's, Rosetails aren't good for breeding, because the mutation that causes the extra branching can affect the scales, and the health of the betta. and, the added finnage isn't good for them at all.
