So last weekend i bought some live rock with corals from a guy who was getting out of the hobby..(corals weren't fairing well in his tank hoping i can save them) I removed the corals from the rocks by breaking the rock where the corals were attached. i then placed the corals in my display, on the substrate attached to the rubble i broke off. I then placed the remaining live rock in a plastic tote with a heater and and airline in case i missed any Zoanthids i could remove later.Also a peppermint shrimp went mia at his house hoping he is still somewhere in rocks.While looking for the peppermint shrimp i found theses worms and what turned out to be allot of bristle starfish.. I need some help Identifying these worms in hopes that i didn't just make a ginormous mistake putting that rubble straight in my display. ( i know stupid but it was getting late and mt QT tank is only 10 gal) So please help ID these worms and since the rock is still in the tote i would like to get the bristle stars out of it which i cant figure out how to do, short of smashing the rocks to bits... Please help with your thoughts
