Custom anemonies

I did not want to use paint effects for all my coral . I wanted to experiment using customized movement. I tried applying a turbulence field to it but I could not make the object work. I then went for a simpler approach using a bend modifier and experimented with expressions which I have never used before but found very useful as it is very adjustable. Initially the coral bent far to fast and I had to experiment with the expressions to get the right speed.
