How to fix tail deformation?

[unreal latch]

I've rigged a tail with skinning and tied the movement to the breath parameter, resulting in a smooth animation, but the tail gets deformed the more it bends. Any way to fix the little bumpy deformations? Or is there an alternative way of rigging that gives similar result without deforming the tail like shown in the videos?

hello, you can manually rig it like skinning but with the glue weight adjusted (going smoothly from green to red)
