Is it normal my chalice is vomiting

[Guss]

Hello all
There is some thing coming out of chalice mouth is normal ? Pictures are not that clear but it a line of black or brow something

I can't tell from the photos but it is possible that the ejected material is zooxanthellae. Something is irritating the coral if that is the case. Possibly too much light or temperature.

I have a chalice that expelled what I believe to be zoox after a 25% water change. Only one coral (out of 60) was affected. No apparent long-term effect, so far.

It looks to either be expelling some zooxanthellae or potentially pooping. Neither are things to worry about unless it continues to do so, and a water change may trigger both of those occurrences.
