There isn't much conflicting info really, IMO. There are simple facts. The fact is that these tangs will out grow a 55g tank...one alone is pushing it. The fact is that most are pretty active swimmers. The fact is that most are relatively aggressive. And another most interesting fact is that we are trying to talk you out of spending more money, and the store is trying to convince you to spend money (at their store). :thinking: Hmmmm, funny how taht happens. Anyway, if you do it, prepare for it not to succeed, and if it does your fish should outgrow the 55 within a couple of years. It may very well work - plenty of things work - just doesn't mean it is the right thing to do. We often have to make the decisions in trying to provide the best we can for our animals. There are plenty of fish I want to have, the could even hypothetically work, but I'm not prepared to risk it. But that is JMO.
