That looks interesting. Would love to see yours if it gets bigger.It's definitely not, it's a Bartholomea annulata. Same family, but different genus. Berghia didn't touch it, the copperband doesn't touch it, it's from the Caribbean, probably 4-5 inches in length, doesn't sting corals, and it has a reflexive reaction to touch that is totally different. Next goal is to track down a Pederson's cleaner shrimp since they have a "hosting" relationship. My sexy shrimp used to do the same too.
