Montipora Eating Nudibranchs
Be alert in checkin new frags of plating,encrusting, and branching montiporas.
As usual dipping all corals prior to entering the tank is the best course of action but sometimes they slip by the standard dip.
I have noticed that these are not as susceptible to my standard dips of melafix. Fortunately after seeing these guys I utilized a couple other dips and sure enough Revive and Bayer are sure fire killers for these guys. I did also try a flat worm killer but with little success. They were irritated and left the coral after some time but did not die until hours later time.
here you can see the skeleton is intact but the flesh itself is all stripped from the bone.
