It is not advisable to breed rose or feather tails. They are actually a deformity and have many issues. Bad scaling is another physical deformity - you can see the scales are not even and uniform.
Looks aside, there are internal issues and you don't want to pass that trait down to offspring. They will be severely deformed, and/or die.
I personally love feather and rose tails. I think they are gorgeous, scales and all. But I have tried to keep 3 and even in good water they have all passed. None lasted any longer than 3 months for me :( Give this boy lots and lots of attention, very very clean and warm water and a good protein rich diet.
