I had a coral vendor telling me there are some SPS if you cut them off a plug, if encrusted, can wreck havoc and may not survive. He also said not to dip the same day as receiving,since the coral is already stressed from shipping, just put it in a QT, and if I decide to dip do it the following day. If that's the case wouldn't the QT be pest infected if the coral had a pest? Cut it off the plug down the line? I received, cut the encrusted coral off the plug, and dipped in Bayer the same day. Two corals browned, I contacted the vendor, he said the cutting and dipping stressed the already stressed from shipping corals.
