If you want to put 3 Tangs in you 90 Gallon you're going to have to stick to very strict water change schedule... and you are still going to have aggression problems I would think.
If I were to try 3 Tangs (I wouldn't) I would go with a Hawaii Yellow Tang, a Convict, and a Powder Brown/Whitecheek. Hippos get way to big, and they are like the Honda Civics of fish tanks (everyone has one).
