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.
They shipped in excellent shape. All went well I'm just hoping they survive my tank and get to destroying the aptasia.
About 4 of them went to eating an aptasia I put in while they were acclimating.
