Phyllodesmium magnum, an Aeolid Nudibranch with a taste for soft corals.

The most interesting hitchhiker in this tank, to date, is the discovery of the Phyllodesmium magnum, an Aeolid Nudibranch with a taste for soft corals. Many thanks to LynnZ at wetwebmedia.com for helping me to positively id this creature. He was spotted crawling up the tank wall toward the overflow. He has not been seen again since. However, the nudi’s tend to take on the look of the coral they feed from. This one did a complete number on my Sinularia.

Although, this is a very interesting specimine, it is not one I would like to see cruising around my favorite corals. I will be removing it when I see it again!
