corals placement

[Maestro08]

cant seem to find a thread about what corals shouldn't be place next to another coral. could someone tell me a link/thread. or simply state your experience because we almost have the same corals because we have the same LFS.

the most commons IMO are:
bubble
frogspawn
hammer
torch
rics
acans
open brains
spiny brains
GSP
zoas
blastos
favias
acans
xenias
cynarinas
coco worm
tube worm
clams
candy cane
plates
gonios
carnations
suncoral
dendro
elegance

here's how i can answer base on my experience.

good -- bad -- safe to any -- bad to any


rics- actino, open brain
spiny brain- candy cane
frogspawn- hammer, torch, bubbles
actino- safe to any

**so far these are my observations. correct me right away if im wrong, and if this goes well, i will EDIT my post everyday to help other reefers on do's and dont's on corals. lets focus more on the common corals available in our LFS. thanks!
