Tentacles Curve Wave Effect

Anyone have any ideas on how to animate curves to perform like a wave effect instead of this side to side animation I did?

Took me a while to find an example but found one by James Curran:

You can use a wave modifier on a curve. If that is not flexible enough, animate it from the material with a vector displacement node.

Answered via StackExchange:

You can use the wave modifier and press play animation.

In my example I rotated my object by 90 degrees without applying the rotation, so to have the desired effect.

Make sure to have enough geometry in your mesh, with evenly distribuited quads.
