Help for soft body modelling / animation

Would someone give me a pointer how to acheive the creation and animatioin os the soft body model - sea anemone - ia n the following video clip.

anenome.mp4.wmv (92.9 KB)

I have tried a soft body object, with wind force, turbulence. Additionally I have
used a cylinder with bone armiture. It works but it doesn’t look too realistic.

Any ideas please.

Thanks

For those who may have a similar enquiry, I realised that I am trying to animate each arm of the animal (yes a sea anemone is an animal not a plant), which could be regarded as more of a tentacle.

Searching Blender for tenticles I found the following tutorial :

It has all the answers I needed, so many thanks to Surfaced Studio
