Is there such thing as too many coral in one tank?

[Gumbies R Us]

There are a lot of tanks I see on here that are filled to the brim with coral, so it got me thinking, can you really have too many coral in one tank? I want to know if you think you are at your coral limit with your tank, or if you feel like there is always room for "one more" coral! Curious to see what everyone says!

I am at a point where I have to decide what I want to keep if I want to get something new. I recently removed a lot of monti cap and encrusting monti to make room for some acros. From a bio load perspective I think its hard to have to many, I think from a space perspective you certainly can.
