Tangs in a 90?

Ah, but herein lies the problem...we can't agree on what's acceptable, and likely never will.
Rather than trying to stop someone from keeping a tang in a 90 (they're going to get one), let's help the reefer learn HOW to keep the tang in the 90. Provide lots of flow, a varied diet, lots of swimming room (and hiding room) and no competition for food.
And I'll give you points on some tangs shouldn't go in a 90, IMO tangs like clowns, sohals, nasos..
but there are enough reports of success with yellows, purples, etc, that we can safely say yes, a tang like that can and often does do well in a tank of less than 6 feet.
Are we agreeing yet?
