Hey, sometimes pinnacle brings in green kenya tree corals (I believe those are capnella, not nephthea that are brought in). Brown nephthea are also fairly common throughout other shops in case you don't mind. I have yet to see orange nephthea (usually those are dendronephthya or scleronephthya). Pink nephthea will have to be bought from Japanese sources (Iwarna brings them in occasionally). Not sure if this is of any use at all but just in case you might want to find other ways to obtain the corals.
