Mandarin - To add or not to add?

[daniella3d]

It's difficult to tell. My yellow tang sliced my beautiful male mandarin to death... now that bastard yellow tang is gone but that prove that you never know how a fish is going to react.

I woudl be afraid of the six line but you know your fish better than anyone and you know if it is aggressive or not.

I have a niger trigger that is a sweetheart and never attacked any one, not even the new fish I put in, so each fish is unique.

One thing is for sure...mandarins don't react to aggression and they will let other fish kill them without too much fighting or reaction.
