ok so I was at a new LFS about an hour from my house and they had a tuxedo nudibranch as they called it. It was in a tank with a bunch of Harlequin shrimp and it was prob the coolest looking slug I ever saw. I instantly wanted it, but since I am smart I waited to come do research. It looks like they are similar to the Harlequin shrimp and Mandarin's in that they need a special diet and most likely don't live that long in a preserved setting like a tank without it. Has anyone tried keeping one of these or known someone who has had success?
