How would you rig this tail?

Hi everyone.

I would want to know how would you rig this:

Under normal circumstances, I would use a SplineIK, or something like that. But I want a special behaviour for this tail. I want that when I make a rotation in the first bone of the tail, the same rotation is reproduced locally on the following bones of the chain, but gradually increasing.
For example, if I rotate the first bone 25 degrees in the X axis, the second bone will rotate 35, the third bone will rotate 45... etc.
How would you face this? I'm pretty sure there's a easier way than doing it manually..., but I don't really know how...

Thanks in advance.

Kind Regards

Not really sure what I'm looking at, but you could use wire parameters or a reaction controller for the rotation.

I tried using the "Wire Parameters" tool (note that this is the first time I use this tool). But I found a quite unexpected result. I wired the X Rotation of the second bone of the tail to the X Rotation of the first bone (being the first bone the master), but when I hit the "Connect" button, I get this result:

You should notice that the entire tail, starting on the second bone, has rotated 180 degrees. Why is this happening? I though that there was some problem with the axis of the bones (like, the X axis of the bones pointing opposite directions, or something like that), but I checked them, and I didn't find any incoherences.
Actually, when I click the "Connect" button, the second bone gets rotated 180 degrees in it's X local axis. But I don't want that...
Any suggestions?

Try the wiring with a new bone chain, that thing in your screenshots looks messed up.

Thanks for your reply.

Well, I just created a new random bone chain (as you told me to), but I think that the problem is not with my original bone chain, it's something else. Immediately after creating it, i tried to wire the second bone rotation to the first bone's (the same I wanted to do before).

Before wiring:

After wiring:

I get the same results. I didn't do anything strange to the bone chain, I just created it, and then proceeded to do the wiring. Is this behaviour normal? What could I be doing wrong?

Kind Regards
