Will Chitons hurt my corals?

[ozorowsky]

I have a chiton in my tank which I hven't seen in a month; today I saw it, and looked like it was sneezing on my coral. It was fat and looking right at my torch and sneezing and this stuff was floating up through the water column. Is that normal??

After further research, this was actually my stomatella re producing

neither chitons or stomatella snails bother corals, in case you were still wondering.
