Proper size for tangs?

[AquaAddict]

IME, rock work set-up is critical. I had a 100 gal bow front corner tank that housed a 3in yellow tang for approx 3 years. It could completely circle the tank outside the rocks horizontally and then vertically through the bridge near the back corner that connected to two side set-ups. It had a couple of other passages that it liked to swim through.

That being said, I shut down tank before it got any bigger.
