Might you swap out the sohal for a lion instead??? And possibly the bird wrasse for a harlequin tusk? The tusk has to be one of the most amzing fish pseices out there. This way, youd have a great aggressive like setup. The angel would grow and be perfect sized for the tank. IMO, lions are much cooler than tangs. They have those cool fins and stripes, and they EAT STUFF:hilarious On a serious note, consider the harlequin tusk. They are awesome fish, but they like to eat inverts (hence the light blueish "tusks".
