Hi everyone, I have a 1-2 inch blue tang, 2 inch yellow tang and a 4-5 inch powder brown tang and I’m looking to add a 5-6 inch purple tang. They say to add the most aggressive last but I’m worried he might bully my other tangs…… can it be done without him killing my other tangs?? I have a 400 litre (105 gallon) tank with plenty of rock and coral to hide in? Any help with this will be much appreciated
