I have a system with a few corals and no fish. The corals seem happy until is time to feed them. I use reef roids Per instructions and spot feed all of them. The Duncans close and start expelling a significant amount of mucus immediately after. Two questions: is this mucus an expected normal behavior or a defense mechanism? In other words, am I harming them with direct feeding? In the picture you can see a floating piece of this mucus. Is it harmful for other corals if it were to land on top of them?
