I have a Yellow and and Regal/Hippo in my 230 and - knocking furiosly on wooden head - I have never experienced Ich on any of them.

So I understand that Tangs are prone to Ich and more so Powder Blues and Achilles which goes along with everything I have heard. In your opinion (I understand this may differ from person to person) what would be considered the more hardy species of Tangs and the least prone to Ich. Can I assume from your recomendation that it would be the Regal and Yellow Tangs. Also would a Naso Tang get too large for a 90 gallon tank? Now that the Saltwater bug has bitten me I am currently in the process of liquidating all the Cichlids from my 135 gallon so that I can change it over to Saltwater.
