just put in a baby 1" blue hippo tang 2day after being in QT for 3 weeks, when i put him in the reef chromis started "tail butting" him which in my experience is a sign of aggression. It looks as if the blue tang is trying to establish territory by pushing the chromis back it looks like they have chilled out a little, now they' re both swimming along and only butt tails occasionally. Is this something i should be worried about? i can probably get the chromis out pretty easily and isolate him for awhile. I think they should chill out if i leave them be...just don't want the blue tang to get hurt.
