Yes my Caribbean blue was 1” when I got it and now is about 3” changed colors also. It went after powder brown, purple and then yellow. Only tang it didn’t bother in my 300reef was the blue hippo who is larger. Today we moved the Caribbean blue in with a 10” Sohal and scopas. So far so good! Will see!Keep an eye on that Caribbean Blue tang. Mine killed a larger Gold Rim. I ended up rehoming him due to him picking on a few other fish in my tank. May have just been a bad individual.
