Hi Johnle

I’ve been pretty lucky with my tangs I have a sailfin too a regal and a Naso all of which get along brilliantly. I think the ones to avoid are the Powder Blue as they can be quite aggressive, and prone to ich, clown tang again pretty but aggressive, and as much as I would want one the Achilles tangs probably the hardest. I’ve found tangs likely to get on Ok as long as the body types are different IE Scopaz tang and Naso probably ok together, Scopaz and Purple Tang maybe not.
