Brain Coral Question

[heather807]

We have a bright green brain coral and every once in awhile it has like a mucus coming off of it. Just wondering what it is and if that's normal.

Is it coming from the mouth? Or the body?
Might be what you are seeing is it is "pooping".

Does it look like the picture I posted in https://forums.saltwaterfish.com/t/225071/what-is-my-brain-doing ? I was told this is the brain pooping.
