Everything I've read says Acanthurus nigricans and Acanthurus japonicus are both very similar looking, but one is a very easy to keep fish, and the other is much more difficult. Unfortunately, everything I've read seems to mix these up - some say nigricans is easy to keep and japonicus is difficult, and other things have it the other way around. Which is easy to keep? Or are the both equally difficult and authors are writing based their person experience which is different for each author?
