Also, would I have problems with having a Purple Tang, Yellow Tang, Naso Tang and Blue Hippo Tang in the same tank?

Mmm, yes…way too much Tang…way too little tank. Though you have likely seen both in smaller systems than yours…the Naso and Hippo Tang both require larger tanks than what you have for their long-term health…both physical and social. You might get away with the two Zebrasoma species together for a time, but the Purple Tang may become a terror as it matures.

I would suggest mixing genera with a small Acanthurus species (e.g. €“ A. Japonicus) or Ctenochaetus species (e.g. - C. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
