Nudibranch perhaps?
Hello all,
I have posted a video of a critter that I had the opportunity to film. The focus gets better after a few seconds. http://www.youtube.com/watch?v=qea_5RyA9z8 I am not sure what the little guy is, my educated (or relatively uneducated) guess is that it is a type of nudibranch. I have see this one in my tank on several occasions, but this is the first sighting in a while. While he is still rather small I would say he has tripled in size over the past month. So, can anyone give a positive id?

My guess is an Thuridilla sp. (perhaps Thuridilla gracilis):

Have you seen what it eats since its been alive so long in your tank? I would love to have some nudi's that are sustainable but 99.999999999999% are so specialized for food you can't keep em alive.

Yep, it's Thuridilla, but there's not enough detail to pin it down to species. The orange rhinophore tips are common to half a dozen species or so. Regardless, it's a harmless herbivore and a very neat one at that.

Thanks everyone! While I have not really seen it eating, i can say that it has been growing steadily with out eating any corals or fish as my setup is still rather young (2.5 months) and until very recently had neither.
