I added a Yellowfin Flasher Wrasse after QT to my display tank. Initially the Blue/Green chromis chased it around for 2 days, then the rolls reversed and the flasher wrasse is now chasing the chromis every time it sees it. It ignores all the other fish in the tank. I thought this was meant to be a peaceful wrasse, so is it holding a grudge for it's treatment when first introduced. Is this even a Yellowfin Flasher Wrasse? Is it a juvenile that will settle down with age, or will I have to remove one or the other of them?
