I have a white tail Bristletooth tang and a Christmas Wrasse that are both in separate QTs right now. I'm wondering how I should add them to my tank. Should I add the wrasse first, wait a week, and then add the tang in order to let the wrasse get established? Or should I add them both at once to diffuse any possible aggression from the resident fish? Currently I have a Swallowtail angelfish, a Midas Blenny and a firefish. They all get along well. Sorry for the bad pics, but they wouldn't stay still!
