I have all kinds of rocks in my reef and I think it adds to a reef in some cases to use not only various shapes but also different forms. I have Fiji, Jakarta, Marshall Isl, Tonga, and Vanuatu.
My favorites are the Tonga Branch and the Vanuatu shelf pieces.
For

disagree with Brad

I've found all rock is the same after it's been in your tank for a year.

I can still see the difference in my rocks after 6 years, not only in shape and density- but the growths of coraline and the differences in things like tube worms and other small critters are different.
Sorry Brad
