Psycho achilles

My achilles has been a model citizen for two years and the last two days has gone psycho. He’s pacing the tank back and forth fighting his reflection on both ends of the glass. He’s leaving the other fish alone but he is stressing them out cause he’s fast. 
 

does that behavior get better over time?

today I noticed he injured himself on rock or coral cause he’s got a bruise on his dorsal fin

I have said many many many times how completely psychotic my achilies was. I found him fashioning a shiv in the back of the display one day.  Mine didn't pace but he would viscously attack ANY new fish in the tank.  angel fish?  KILL!!!   blenny..  KILL!  who attacks a blenny?   Dude was out of control.  I had to add 3 new big tangs at once to get any new fish in there.  

My guess is he will chill out over time.  

But for the record, Achilies and powder blues still hold the top of the list for aggressive tangs.   People thing the sohal is agressive....Pffff  homey got nothing on the PB.

Maybe your fish are picking up traits from you.  Just a thought. 🤷‍♂️
