Definitely a nudi. I can't say what species though. From the look of the two "bubble tip tentacle" things up by its head makes me guess that it either go after BTA or mojano anemones... most likely mojano. Hopefully that might help you narrow your search.

definitely not berghia

Does this guy look similar to the above pics? The more I read about this critter things seem to fit.

Aeolidiella alba
