Ey guys this tentacle keeps moving around its very small so it will be hard to see it's right in the middle many thanks to whoever finds out what it is.

The whole thing looks like a aspista anemone. is it shaped like a anemone or one strand?

 

[Paulyboy123]

It's a bunch of little strands constantly moving
