coral warfare

[scuglass]

i have a few lps in my tank and am wondering how far these corals must be kept from other corals. i have 2 diffeerent candycane frags favia acans frogspawn (5 heads) and a closed brain. can these corals be kept close to other types of corals softies and sps or do they attack all other corals. just wondering how so many people find how and where to place certain corals and have them packed in so tight.
