mantis shrimp beat up my hammer coral?
Today I saw that in two areas, the hard skeleton of my hammer coral was broken off. The largest broken area is about one inch in diameter, and extends in less then 1/2 inch. My husband indicated that he noticed a smaller segment yesterday, and today it was tripled in size. Otherwise, this coral has been perfectly healthy.
I did notice a mantis shrimp peering out of a hole about 2 weeks ago, and about 5 days ago, I saw him start to wander around the tank. It was my plan to try to capture him ASAP, but I haven't had time until today.
Because the skeleton is so hard, I could not imagine any other creature doing that type of damage, but I was unaware that a mantis would attack a coral? Have you seen this before?
Is there any harm in moving the coral to my refugium for a little while, for safety? Or should I formally quarantine it? Do I need to do anything else about the broken sections, or will they heal in time?
