You definately don't need to worry about a Sohal Tang being bullied by anyone for very long. This is likely the "toughest" tang on the block, in fact a 180 is actually borderline for a Sohal (up to 2ft in the wild). This fish will get big and aggressive quickly. I wouldn't plan on adding any more Tangs once he gets his foot in the door. Wonderful, active, and beautiful fish though.
