Is it necessary to quarantine a frag of Trumpet coral? After much research, I ordered two neon green Caulastrea heads from Tidal Gardens as my first coral for my reef tank. All of their coral is grown separately from fish and invertebrates. I have a QT tank currently setup for a diamond goby and peppermint shrimp I recently purchased. Is it necessary to QT the frags, or will a dip in Coral RX be sufficient?
