Powder Blue or Brown

[Dave VG]

Which one is less aggressive than a purple tang?

 

[SIguy]

Neither are. Most tangs are very aggressive. IMO you would be better off witha brown though. It is less likely to get Ick.

I love my powder blue. He has been a very healthy fish from day one but he is the tanks bully. If my sail fin wasnt bigger than the blue he'd have killed it by now. As it is the sail fin just ignores his threats.
