same here, i recently upgraded my 72 to a 125, also with a more open scape, although the corals i plan on growing out might take up a good amount of space. i really love the length of the tank, and my bannerfish seems to really enjoy it too. it looks HUGE compared to the 72. my banner and the foxface i know are nowhere near their adult size, thats why ive been hesitant to add any more.
