I got the package picked up and all 6 berghia are alive!! I guess I hold the record for the longest time in shipping at 6 days (thanks to customs and FedEx).
I've put them in the tank and there were 3 egg packs as well.
The berghia rrived wonderful. All three were fine and I was able to hand feed them one small aiptasia each during acclamation. I got to see first hand how they chow down on them. Wonderful stuff.
