I've had one in every reef I've ever had, along with the other deepwater butterflies (declivis, burgess, tinkers, etc). They are amazing fish with a lot of personality and love to be front and center begging for food. I will say, however, that this is the first one of 5 that has decided to pick at a few corals. He's very selective on what he picks at but still does pick at a few. I guess 1 in 5 ins't too bad.
