I only fragged when stuff was going to grow into each other. However I kind of got sick of it and just sold off large colonies to make room. Now I mostly just let nature take it's course and let stuff grow into each other and whichever coral is stronger, wins. I just actually gave away all the crags in my frag tank so thy I could hit off the power heads and lights to save energy.
