Stocking list thoughts?

[NIWID]

Anyone see any compatibility issues with this stocking list? Is it ok to keep these 4 tangs in a 6ft 170 gallon tank?

Niger Trigger
Azure Damsel (5)
Watchman Goby
Lawnmower Blenny
Maroon Clown (2)
Yellow Foxface
Hippo Tang
Purple Tang
Powder Blue Tang
Kole Tang

Yellow and Purple could squabble as they are both Zebrasoma. Powder Blues can be fairly aggressive to other Tangs and are very prone to disease. Also not sure how that Niger Trigger will do with the other fish as they can be very aggressive.
