I work up to this looking at me i have been told it is some type of flat worm. I have added a little GSP frag, 6 chromis, and an urchin in the past week. Can anyone help with what type of flat worm this is and what my next steps should be? I did dip my coral before adding it. When I caught this critter it got really small like maybe the size of the head of a sewing pin. He is currently in a jar until i figure him out.
