well i went here :
http://www.cites.org/eng/append/index.shtml
then looked at the appendex and it looks like only the following corals are restricted (assuming I am looking in the right) place:
HELIOPORACEA Blue corals
STOLONIFERA Tubiporidae Organ-pipe corals
ANTIPATHARIA Black corals
SCLERACTINIA Stony corals
CLASS HYDROZOA
(SEA FERNS, FIRE CORALS, STINGING MEDUSAE)
MILLEPORINA Milleporidae Fire corals
STYLASTERINA Stylasteridae Lace corals
but from what i have read in other posts live rock needs a CITES permit and thus anything attached to it (like the zoo's) will likely need one...again
not sure if I am correct here, can anyone confirm?
