I’m not sure if this is the right place to post this but i noticed this in my back chamber of my AIO. any idea what it is? Is it safe to keep in the tank or should i remove it?

Medusa Worm. in the sea cucumber family. Harmless filter feeder but if ripped during removal can release toxin in tank. I have a few and just left them alone with no issue.
