I have one still, he is very aggressive, he ate 2 of my Peppermints & forced me to extract a Six line wrasse before it was too late, chased around my Magenta Dottyback, but gave up finally and left him alone, what’s weird is that he likes the Cleaner Shrimp, in a good way, he takes a cleaning every now and then from him, and I also have a Coral Banded Shrimp that he doesn't bother, my guess is that their too big to mess with and plus they were there first.
