Hi. Really need some help please. This plant looking creature comes out at night. It’s no where to be seen during the day. The plant like stems actually seem to pull things into the center like an octopus would only it’s not that. So what is it and do I need to get rid of it? If so how? Thank you!

+1 it's a cucumber. I've had them hitchhike on my gulf live rock. They're cool little guys but sadly they don't last long.
