Aquascaping-change

[daddy01]

Hi,
I am new to reefing and am in process of changing from FOWL to nano.
I have added a Frogspawn and Ricordio (yuma) and Nephlea so far. My tank is a 30X12X21(17) with 4" sand/coral substrate=28Gal(?). I have a 130W Auqalight. I have frogspawn 7-8" from top and Ricordia same and the Nephlea 10" down in tank.
Now I am contemplating adding some Bubble coral, Red Goniopra, Green MoonStone hopefully.
My question is how much re-arranging can be done on aquascaping to accomodate these additions?

you can re arrange your aquascaping how ever you like. its not set in stone. alot of people alter their aquascaping many times before they leave it alone and then in the future when corals grow and you add others sometimes you still have to change it around

What he said.

As well, think twice before getting some goniopora. It's a difficult coral to keep, apparently. Check out this (http://www.advancedaquarist.com/2005/10/aafeature2) article.

Cheers!
