Aggressive Heniochus ?

[rotorjockey]

Got 3 new heniochus from SWF today.
After lengthy acclimation then release into a 125 fish only, they almost immediately started bullying my Naso Tang which is over twice as big as them and my Dot-Dash Butterfly which is also larger.
Everything I have read about them is that they are peaceful. Did I miss something somewhere?
I have turned off the lights and covered the tank to put them to bed for the night. Maybe better in the morning.
Other fish in the tank that they are leaving alone:
1 Large Diamond Goby
1 very small Blue Hippo Tang
1 small Panther Grouper
1 4"-5" Sweetlips

All fish have different personalities, The fact that there is three maybe be helping them. You could try rearranging the rock to make them all reestablish territory but you may have to remove the Naso if things get too rough.

I've been watching them closely.
They aren't so much interested in the Naso any more. Now it seems to be the Dot-Dash.
And the attention they are giving him is not nipping or biting. It looks much the same as when a fish with ich scratches himself. They come up along side of him, then with a quick flip of their tail, they rub up against him. It doesn't appear to do any damage. It just seems like they are being a nuisance.

Trying to find who is boss. My clowns did it to each other.

I realy would not worry unless you are seeing aggressive marks on the dot. Heni's are not aggressive by nature, but they will chase when they are first introduced to a system with other fish though. They do "clean" other fish, but not bite. Is that what you are seeing? I would not be overly concerned about it.
