Nudibranch ID… sans pic?
Hi Crew, Today I found a Nudibranch in my tank and was wondering if you could help me ID it and figure out whether or not it’s harmful. It is about an inch long, white or very light cream in color, and has these sort of little fuzzy branches on it’s back. We have several corals, a colony of xenia, a branching frogspawn, a large mat of green star polyps, and a colony of blue mushroom polyps. None of the corals seem to have been eaten, and all of the live rock we have has been in the tank since we started it six months ago. I believe the rock to be Caribbean in origin but I’m not quite sure. The tank is 330+ gallons in size so the toxic death doesn’t worry me as much as the coral predation. I looked at your fact sheets, and it looked the most like Pteraeolidia ianthina, but less elongated. Please let me know if you have any idea as to what it is, what it feeds on, and whether I should remove it or not. Thank you for you time. -George G.
