Hi Dr. Rudman,
Here is a nudibranch that was introduced accidentally into my aquarium. Sorry for the poor photos, you can see the features pretty well.
It's less than an inch long, has the purple-white-yellow pattern you see, the "bunny ears" antennas and a gill structure in the rear. The cool thing is it's been living in my reef tank for more than a year and it's grown, so it must be eating something. Can you ID it?
Thanks and Regards,

Your animal is Durvilledoris lemniscata. I am very surprised it has lasted a year or more in your aquarium as it is a chromodorid nudibranch, and like all its relatives it feeds on particular sponges. apparently it must have hitched a ride on something, a rock perhaps, with its favourite sponge food. Either the sponge is particularly hardy and has found away to live in your aquarium, even while being constantly eaten by your nudibranch. Perhaps you should keep an eye on it and see if you can find what it is eating. If it has a 'home territory' in your aquarium that would be a good place to look.
