My flame chased my new wrasses the first week. First day was intense. I'd say depending if their fins are nipped badly or not give it a little more time. Try keeping the lights off for a few days. After about maybe 5 or 6 days he stopped.
I just took out my starcki damselfish, had him for a couple months but wouldn't let two of the wrasses move around more than 10% of my tank. And one of the wrasses fins were getting bit pretty bad, so he had to go. Put half my water and most my rocks without coral on it in a brute yesterday and caught him, along with a sally lightfoot crab.
