I'm moving soon and I need to ship some of my corals to their new home. The new tank is set up already. I'm worried about shipping the stoney corals because I fear they might puncture the bags. Should I find some way to float them in the bag? How thick mil bags should i use? The corals include some SPS and some LPS corals, none are bigger then 4 to 5 inches. Any tips on shipping stoney corals would is appreciated.
