LOL, funny guy....No I kind of agree that anything can work out within reason, that's not to say you should put a Sohal with a Clown Tang in 100 or an Achilles with a Powder Blue in a 100. But as long as basic tank size needs are met, and you don't try to mix tangs that look alike (such as the 2 examples I mentioned), most tangs from different families can co-exist wonderfully. I certainly think Powder Blue and Yellow, or Blue and Yellow can coexist given the right tank size. In a 100 I like Hippo with Yellow a little better, Powder Blue are very active fish that do better in a bit larger tanks.
I think when you introduce is important too, that is where T316 and I differ a bit, I have always found any Acanthurus Tang (such as Powder Blue) to be more aggressive (T316's Yellow I believe is more aggressive). I had an established Achilles in a 125 and tried to add a smaller Yellow, the Achilles killed it, where as I think if the Yellow were in first it would have worked, but that was many years ago.....I digress....I think a Hippo and Yellow are worth a try in a 100...I would prefer a larger tank for a Sailfin or a Powder Blue.
Good advice, and no, I was not being sarcastic. I was being serious in that you do have more knowledge/experience in this area.
Also, this thread is kind of confusing....I think the OP has a 100 g., but then JoJo posted the question about the sailfin and he has a 135.
