Duncan coral spawning?

[Heatherabel3]

The larger heads on my Duncan are all simultaneously releasing a clearish thick substance? Are they spawning? If they are is the entire coral one sex or can each head be it's own sex? I don't know the chances of baby Duncan's popping up in my tank but it would be cool if it happened.

Nope, more than likely a stress response. If you said brown, I would tell you it was probably just pooping lol.
