The PBT is fine i moved the nori clip down the other side of the tank so it goes down there now also added 2 new fish i'm upgrading sometime next year to a 5/6 footer once my goldflake grows abit had a little bit agression from the PBT with the 1" goldflake which was kinda scary but put a mirror up PBT went crazy with itself it had 4 white lines down where the blue is never seen that before the lines have gone now dnu if that was stress or anger thinking another tang was in the tank anyone ever seen that before?
