I don't agree with going against the general guidelines that have been laid out, i typically follow them. However, I think that going against the grain is sometimes how new and interesting things are discovered. No two fish (Especially Tangs) are the same, they all have different personalities and requirements. There is no true Law to nature/animals. No one can say that x+y=z 100% of the time. I have a 125 Gallon with 4 Tangs in it, There is absolutely no aggression among them, and there never has been, they tend to swim together primarily. I know that having 4 tangs in a 125 is pushing/breaking the limits, however I took the chance and it is working out for me. If at some point, things turn sour as they grow larger, I'll do the right thing and re-home them. But until that day, I'll continue to enjoy the 4 most personable fish anyone could ask for.
