I have a 135G FOWLR tank and presently have a PBT 3 1/2" and I would like to add a Gold Rim Tang. I know it's iffy and I may lose one. When I introduced a lemon peel angel and a Heniochus the PBT chased them relentlessly until I put a tarp over the tank for 24 hours, and that worked great. I made a tank divider out of plexi glass with the exact dimensions of the inside of the tank, and drilled holes thru out every 2 " so I could trap fish in one side of the tank to catch them without ripping all my rock out. I was wondering how things would go if I were to put the PBT in that area(probably about 20 gallons worth of space) while the new tang roams freely checking out the tank for a couple of days. I know they are both very aggressive. Any thoughts or tips?? Thanks in advance!!
