Thank you all for your comments. As I was inspecting the tank more I found a good number of these guys but they almost looks like a bunch of snails. They have a cone shape with antennas at the wide end. I did also see what I think is a tiny thin worm which I could being the bristle. Either way looks like I have some new members on the tank.
