Re-aquascaping?

[reefgirl189]

I'm getting bored with my aquascape. I want to open it up a bit more. It's actually a very nice aquascape - loads of caves and cool spots - but I feel like it kind of sucks for coral placement as I can't see the other side of the rock. Plus I'd like to get a couple more fish eventually (a few tangs for sure) and feel that they need more open swimming areas.




So my question to all of you is this:

How often do you re-aquascape? OR Is it just a dumb idea?
