As the name implies they can’t easily be removed by scrapping as each “ arm/ head ) will grow a new tree from being broken. Best to kill them with deworming medication .
They are dangerous to shrimp and very small fry. They sting fish and only a very very hungry fish will eat a couple.
Do not panic. They are no big deal but you want to keep them to a minimum. Don’t try and scrape them off.
