I have found a new creature in my reef and am wondering if its "Friend or Foe"? It moves like a snail, seems to have little antennas but it looks soft and mushy, no shell, what could this be, i would say its about 1/2" long. These are the best pictures i could take before it went back into the rock.
Thanks in advance for all of your help.
