Wanted to add another tang to my 475 and wanted some advice. I currently have 1 unicorn, 1 naso, 1 purple, 1 orange shoulder and 1 powder blue. The fish i'm worried about is the powder blue. I've tried just one tomini before and the powder blue went nuts. I wanted to try adding 3 tangs at once to see if this helps. i have the tomini, a white tail bristletooth and was looking for 1 more to add simultaneously to disperse agression. Any advice? I have 3 acclimator boxes i'm gonna use to try to get the fish socialized with the others for a few days. Any thoughts on what the 3rd fish should be? They have a nice chocolate at the store? Thanks.
