Mandarin - To add or not to add?

[doch]

You know... I find it funny that six lines are considered an aggressive fish. I never once had a problem with the one that I had. New fish, old fish, no problems. Judging from that experience, I'd say that you'd be fine. I find that my pair of mandarins are among the fish that none of the other fish seem to even notice. I have a Lyretail Anthias that is a real jerk to every fish that I have, but ignores the mandarins. The Antias has chased my black capped basslet into hiding to the point that for 3 months, I thought he had died... and then he showed up breifly the other day. To me, there seems to be something about mandarins that makes all of the other fish oblivious to their existance. I should also mention that I have 4 wrasses in with my pair of mandarins without issue. Oh, and a large regal tang... and 4 angels. All in a 50gallon. (alright.... 2 angels, and it's a 160... hahaha... bring it tang/angel/mandarin/wrasse/everything police)
