Well it concerns me to hear all of this. I guess I knew that I would open up a can of worms when I mentioned a tang. What concerns me is that my LFS that I find to be the most trustworthy in town told me that my 75 gallon would be OK for the Powder Brown, but not a Powder Blue.
Aside from the tank size issue, I'm a bit concerned with the browns being soo fragile. This disappoints me because the reason I wanted to move to a 75 from a 55 was so that I could obviously have more corals and primarily so that I could house some fish species that I could not with the limitations of a 55g.
I really like the tang family, so what are my best bets as far as Tangs are concerned in my 75 mixed reef?
Any suggestions?
And thanks for all of the responses thus far.
