It looks like there have been some posts on this fish over the years, but very few, and not in a long time. Based on the profiles I've read on the web, these may be exceptionally aggressive. Are they that tough? Could they get along in a Tang community (bigger fish like sexfasciatus, fronts, and some calves [which i'm worried about!]). If anyone has experience with these guys, I'd love to hear some feedback.
