So anybody have long term success with Clown tangs?

[Dearth]

Ironically I was just talking with a friend of mine in the states who runs a few SW aquariums in his home and he has both the Sohal and Clown tang in separate tanks and says that he has lost quite a few Clowns to a disease called hole in the head disease thought he was joking at first but he told me that even with best of care these guys can develop the disease lovely fish to look at but difficult to raise.

His Sohal on the other hand easy to care for never no issues with disease but nastier than hell has killed several wrasse and severely injured his prized red tailed Trigger fish and even bit my friends hand hard enough to draw blood.
