    What is this worm in my aquarium?

    Good day! Please help me identify what kind of worm this is? Is it harmful or useful? How to deal with it? It is green and has a red dot on its back. My aquarium is only 1.5 months old, but there are a lot of these worms. I think they got into my aquarium through the corals.

    Worm ID?

    I've tried to ID these guys, but I swear they look like 10 different worms when I tried comparing pictures. This is through one of those phone connected microscopes, as the worms were crawling through the sand. They're about 0.5in long, super thin, and white to the naked eye.

    Creature ID

    Is this a fancy worm or a brittle star? I see something that looks like tube feet, so maybe a star? I do not know where i got it from, i saw no stars in chaeto, this piece of rock(the only live rock i bought) or on the small rock with zoas that was gifted to me. Will it divide into more specimens?
