I bought mine from Saltwaterfish.com and it is doing fine ~4 months later. I quarantined him (and other fish) with copper treatment for 2 weeks, then an additional 2 weeks without copper. It ate Mysis shrimp from the beginning (albeit without enthusiasm). It took at least 2 weeks of exploration in my aiptasia-infested tanks before he ate any, but once he started, they disappeared rapidly.
