Reefing newb
Okay, so I found some sort of creature in my aquarium, and I was hoping that you all could help me identify it. It hides in the LR in the same crevice, and I've never seen it come completely out. It appears to have multiple "arms". I've seen up to three "arms"/tentacles at one times. The tentacles are striped with alternating burgundy-brown then white repeated. Yesterday, I ripped part of the creature's tentacle off with a pair of tweezers. Pictures are below:
